What Should I Feed My Cat?

Understanding what you should feed your cat is important as a good diet generally tends to promote and maintain good health. A cats metabolism is so heavily specialised in obtaining nutrition from meat, it’s important to choose the correct diet. Most cats are notoriously fussy — so getting a healthy and suitable diet into them (that they will enjoy) isn’t always as easy as it seems… and this might explain the sheer range of diets currently available on the market!

Cat nutrition 101

Cats have evolved as obligate carnivores, meaning that they need certain nutrients only found in animal tissues to survive. In particular, key nutrients that cats need include:

  • High levels of protein in the diet (as much as 30-40% higher than a dog).
  • Specific proteins, e.g. taurine and arginine. A taurine-deficient diet leads to blindness, heart disease, and a weakened immune system, while feeding a single meal deficient in arginine can lead to liver failure and seizures.
  • Certain vitamins that they cannot make themselves, e.g. vitamin A (needed for vision).

In general, the best meal for a cat is a meat-based one, although using appropriate cereals and oils (as in many commercial diets) to balance the calorie provision is perfectly acceptable. Cats cannot thrive on a vegetarian, or survive on a vegan, diet without synthetic supplements.

So, with this vast array of options – where do we start? It can be a daunting decision. However, to make it easier, we’ve selected certain key features to consider below.

What should I feed my cat?

How old is your cat?

As we grow up from infants into toddlers into children into teenagers and into adults, our nutritional needs change. And of course, as we age, they change again. This situation in cats is exactly the same. Kittens typically need high calorie and high protein diets, with specific minerals such as calcium, for growth – more than at any other age. Adolescent active cats need more calories than adults; whereas older cats often benefit from limiting the amount of dietary protein to protect their kidneys. That’s not to say you need to buy a new food every six months or so (well, except for keeping up with those fast-growing kittens!), but that you need to be aware that your cat’s dietary needs will change.

What kind of lifestyle does your cat have?

Is your cat out and about, hunting and playing outdoors? Or are they more of a sofa-surfer? The more time they spend outside, the more calories they’re likely to require. HOWEVER, also ask yourself are they being fed anywhere else? Some cats have a great knack for persuading neighbours that they’re a poor starved stray, and may work their way from house
to house getting a fresh meal at each one… so keep a close eye on their waistline!

Does your cat have any dietary sensitivities?

While food allergies aren’t that common in cats, they do occasionally occur, so it’s worth being aware of what the protein source in their diet is.

Is there anyway your diet may be able to support and manage an existing issue for your cat?

Many health conditions have been proven to respond to certain balances of nutrients in diet – in particular, cystitis, and many bladder stones can even be dissolved by feeding the correct diet; cats with kidney disease will also benefit from a specialist renal diet that contains lower levels of high-quality protein, low phosphate, and altered salt balances. These specific food formulations are called “prescription diets”, and are available through us
(please don’t feed a prescription diet except on veterinary advice though!).
There are also diets available with specific nutrients (e.g. tryptophan) to help manage things like stress and anxiety.

Is the diet you are considering labelled a complete diet or a complementary diet?

A complete diet does what it says on the tin… it contains all the nutrients your cat needs, in the correct ratios. A complementary diet does not, and needs to be combined with another type of food to give a balanced meal. In general, most manufacturers provide complementary biscuit and wet diets, that you mix together. The problem with a complementary diet is that it assumes the cat will like both parts equally… which isn’t always the case!

Remember that your cat is an individual with their own unique requirements. No-one is better placed to know what they need than you and your vet — who both knows your cat as an individual. So, if it all seems a bit too much, and you’re not sure what the best option is — talk to one of our team! We can carry out an individual nutritional assessment for your cat and determine what their exact needs are, and then work together to find the best diet for them.

Common Toxins Dangerous To Your Pet

Certain types of food and household items can be unknowingly toxic to your pet — read our list of the most common toxins dangerous to your pet below.

If you think your pet has ingested one of the following please contact your vet immediately. If you are concerned your pet has eaten something poisonous not listed please use our online poisons guide for advice.

FOOD AND PLANT TOXINS

  • Chocolate – causes heart rhythm abnormalities and nervous system signs (eg excitement, tremors, seizures). Just 15g of dark chocolate can be toxic to a 10kg dog.
  • Onions – cause anaemia by destroying red blood cells.
  • Garlic – believed to have a similar effect to onions.
  • Macadamia nuts – in dogs, cause weakness, inability to stand, vomiting, depression.
  • Avocado – fatal in birds and rabbits. Avocados contain a substance called persin which is highly toxic.
  • Grapes and raisins – can cause kidney failure in dogs.
  • Raw or undercooked meat – diarrhoea and/or vomiting (due to Salmonella or e.coli bacteria).
  • Fungal toxins (mouldy food) – diarrhoea, tremors, seizures.
  • Bread dough – disorientation, depression, weakness, coma.
  • Acorns – diarrhoea, kidney failure.
  • Lilies – have been shown to cause kidney failure in cats.
  • Brunsfelsia – (“yesterday-today-and-tomorrow”) – diarrhoea, seizures.
  • Oleander, rhododendron, azalea, crocus, foxglove, hyacinth bulbs – Heart problems.

HOUSEHOLD TOXINS

  • Antifreeze – causes kidney failure, cats and rabbits need to ingest only very small amounts to show symptoms.
  • Tea Tree Oil – depression, weakness, incoordination, muscle tremors.
  • Pyrethrins, Permethrins – usually found in supermarket / pet shop flea products, toxic (especially to cats) if ingested; causes salivation, tremors, and seizures.
  • Paracetamol (panadol) – toxic to the liver and interferes with oxygen transport, can be very quickly fatal in cats.
  • Ibuprofen (nurofen) – depending on amount eaten, can cause gastrointestinal ulcers, kidney failure, and/or seizures.
  • Aspirin – can cause gastrointestinal ulcers.
  • Bleach and other cleaning products – many of these chemicals are highly acidic or alkaline, and can cause tongue and mouth ulcers when licked by dogs or cats.
  • Rat poison– causes blood clotting problems, seen most commonly as internal bleeding, or blood in stools or urine, or vomiting blood.

My Cat’s been Diagnosed with Hyperthyroidism – What Next?

Hyperthyroidism is a relatively common condition that we see a lot of in middle-aged to older cats. As the symptoms can be quite subtle initially, it is often mistaken for ‘natural aging’ or perhaps a stomach upset.

At first, owners may even be pleased at the change they notice in their cat, who is suddenly more active than before and has a bigger appetite. However, over the weeks it may be noticed that they are acting hyper, have been very vocal and seem to be losing weight. A few loose poos in the litter tray may have been found and the water bowl may need filling more regularly too.

When presented to us in the veterinary clinic, we will check these kitties from nose to tail and look for some of the tell-tale signs of hyperthyroidism, such as a fast heart rate or a small lump in their neck region (a goiter). As a first step, we will recommend a general blood test, which will include a thyroid hormone check.

If your cat is hyperthyroid, blood results will show a thyroxine (thyroid hormone) level that is much higher than it should be, confirming our suspicions. As hyperthyroidism negatively impacts a cat’s quality of life and is a progressive disease, it is important to address it as soon as possible.

My cat has been diagnosed with hyperthyroidism – now what?

Thankfully, this is a very treatable disease and there are several different options available to owners. Which route to go down will depend on your cat’s age, their overall health and temperament, convenience, accessibility and finances.  Most commonly, hyperthyroid cats are managed with long-term medication. This is available in several forms, including tablets, oral liquids and even a cream that is applied to the ears. The medical management option is generally very safe and is achievable for most owners. Cats do require frequent re-checks and blood tests throughout their life, ensuring the dose of their medication does not need to be altered.

For some, daily medicine may not be practical. This is true for owners with busy lifestyles or for cats that are not particularly co-operative! Luckily, there are several other options available:

  • A surgery whereby the affected thyroid gland(s) is removed is a possibility and this procedure has high success rates. Owners will be advised of the potential complications of both the anaesthetic and the surgery itself. Though this surgery can be quite expensive, in middle-aged cats it will mean less money spent over time as there should be no need for any long-term medicine once the surgery has been confirmed a success.
  • Another potential treatment is Radioactive Iodine Therapy. This is a specialist procedure that is only available in certain referral centres and can be cost prohibitive to some. For most, a single painless injection of the radioactive isotope is all that is needed to solve the issue forever. Afterwards, all treated cats must stay in the referral centre in isolation for several weeks and handled minimally as they are classed as ‘radioactive’.

It’s important to note that even those owners who opt for the surgical route or for the radioactive therapy will have to first stabilize their cats using medication. Though it can be tricky to medicate some cats, our staff are more than happy to discuss the various options available and to demonstrate how to medicate. Items such as pill poppers and pill pockets can be real game changers.

On top of what has already been discussed, there is also a dietary treatment option available to manage hyperthyroidism. It is a safe and effective way to manage hyperthyroidism as it contains limited amounts of Iodine. The issue with this therapy is that if cats eat anything else (treats, food from the outside or food from the other cat’s bowl), it becomes ineffective. Cats with other medical conditions may not be appropriate candidates for this diet but for many, it is a convenient choice.

With hyperthyroidism being the most frequently seen hormonal disease in cats, it is a condition which we are very familiar with and which has many effective treatment options.

Whichever road you and your cat decide to go down, we will be here to help and guide you every step of the way.

Chronic Kidney Disease in Pets

Lots of cat owners know that kidney disease is a big problem for their feline friends, but it might surprise you to know that it is a problem in dogs too. Around 1 in 40 cats will be diagnosed with kidney problems, whilst in dogs, the number is much lower at around 1 in 100. This makes it one of the most common diseases we see in practice, so we thought we’d take the time to tell you a little more about it.

What is Chronic Kidney Disease?

Chronic Kidney Disease (CKD) is also known as kidney failure or renal failure- the end result of kidney damage over time. It is known as chronic because the damage is usually sustained over a long period of time, unlike Acute Kidney Injury which occurs very quickly. There is no way to prevent kidney disease specifically, although early diagnosis certainly helps. A yearly urine test in elderly pets can help to diagnose problems before symptoms start to appear- just ask our reception team for a urine collection pot.

Could my pet have CKD?

Animals with CKD often don’t show many symptoms at first, and pets can be in quite advanced stage of the disease by the time they are diagnosed. Older pets are more prone to CKD, and cats get it more commonly than dogs. Pets with heart disease, high blood pressure or severe dental disease are more prone to getting kidney problems. There is also an increased risk if your pet has had previous problems with their kidneys. The most common symptoms are an increase in drinking and urination, smelly breath, weight loss, and inappetence. However, other symptoms such as lethargy, vomiting and poor coat condition may raise suspicion of a problem.

If you think your pet is showing any of these symptoms, it’s highly recommended that you book an appointment with one of our vets.

How is CKD diagnosed?

We’ll definitely want to check your pet over to rule out other causes and confirm your suspicions. Clinical dehydration and kidneys that feel smaller or ‘knobbly’ are both evidence of a problem, but it’s also important to listen to your pet’s heart as heart disease and renal problems sometimes go hand in hand. As most of the symptoms of CKD are also symptoms of many other diseases, we’ll probably suggest a blood test to get more information. We can then check that the liver and other organs are normal. If the kidneys are struggling, we will see a rise in two chemicals in the blood- urea and creatinine. Combined, increases in these two chemicals suggest renal disease, especially if there’s other evidence. We may also see upsets in some enzymes and anaemia associated with renal failure. We also like to check a urine sample. Pets with CKD have very dilute urine because the kidneys are no longer concentrating the urine correctly. We can measure the concentration of urine, and if it is very dilute this lends further evidence to a diagnosis of renal failure. We might also send the urine to a lab for further investigation and check your pet’s blood pressure.

How is CKD treated?

Unfortunately, there is no treatment for CKD, but there are ways it can be managed. At first diagnosis your pet may be quite sick, so we often advise that we hospitalise them and put them on intravenous fluids (a drip). By doing this, we are trying to correct any dehydration and flush the toxins that have built up out of the system. This usually takes 24-48 hours.

If a pet is not too ill, or after they have been discharged from hospital, they are put on a home-management plan. The most important thing is to support the kidneys by providing a kidney-friendly diet. These diets are low in phosphorus and contain a moderate amount of high-quality protein. We will advise you on diet at discharge from hospital. Your pet may also be put on medication to lower blood pressure or stop too much protein being lost by the kidneys.

What is the prognosis for animals with CKD?

The prognosis is dependent on how ill your pet is, and how well they respond to treatment. There is no doubt that chronic kidney disease is life-limiting, but many pets can live for months or even years with the condition. The important thing to do is to monitor their quality of life and keep checking in with us to make sure they aren’t getting worse or there isn’t more we can do to help.

It’s also worth considering that some medications shouldn’t be given to animals with renal problems. Many medications pass through the kidneys and can damage them further if the kidneys are struggling to process them correctly. If your pet is on any medication that we don’t know about, such as store-bought flea treatments or supplements from an online pharmacy, it is best to check with us that they are still safe to give.

Goddard Veterinary Group Wellness Screen – What are we looking at and why?

Blood testing is an incredibly useful method of gaining more information about the health of a pet. Our vets will often run blood tests when an animal is unwell to help find out the cause of their illness in order to treat them effectively. However, there are situations when it might be advisable to run blood tests, even if your pet does not seem unwell.

We all know the old adage ‘if only they could talk’. Unfortunately, as our pets cannot speak to us, it can be difficult or impossible for both owners and vets to pick up on the subtle early signs of some illnesses, which often cause no noticeable changes in a pet at home and may not even be detected by a vet physically checking over an animal. Many chronic (long term) diseases can be ‘subclinical’ for months to years, meaning they do not cause any signs of ill health. If we are able to detect disease at an early stage, there is often more that we can do to slow down how fast that disease progresses, and in some situations even prevent an animal becoming unwell at all. Blood tests are a quick and non-invasive way of being able to find out more.

What is included in the Goddard Veterinary Group Wellness Blood Screen?

  • Haematology: This part of the blood screen counts different cell types in the blood. Many diseases can cause levels of red or white blood cells to be high or low. For example, a low red blood cell count (anaemia) can be caused by a variety of conditions. The haematology can give more information than just numbers of a type of cell – the average size of the red blood cells can provide more about the possible causes of anaemia, for instance.
  • CHEM 10 blood biochemistry: This measures ten different values. These include blood protein and sugar levels, which can indicate if a pet is diabetic, for example. ALP and ALT are liver values which can be high in primary conditions affecting the liver but can also be high for a variety of endocrine (hormonal) disorders, such as Cushing’s disease, an over or underactive thyroid, or other diseases in the abdomen, which can have secondary effects on the liver. Urea and creatinine are also checked to screen for kidney disease.
  • SDMA: This is a new biomarker of kidney disease and is something we are able to include as part of the health screen. The other kidney values of urea and creatinine are only increased when 75% (three-quarters) of kidney function has been lost, whereas SDMA increases when just 40% of kidney function has been lost. Chronic kidney disease (CKD) is a very common problem in elderly animals, particularly cats, and this test means we can pick up reduced kidney function at a much earlier stage. Whilst kidney disease will progress with time, if detected early there are many measures our vets can recommend being instituted to slow this down, such as changes in diet or medication.
  • Thyroid hormone level (Total T4 or TT4) for cats over 8 years old: hyperthyroidism (an overactive thyroid) is a common problem in geriatric cats. The thyroid gland is located in the neck and produces thyroid hormone. An overproduction of this can cause many changes such as weight loss, increases in thirst and appetite, and changes in behaviour and coat condition. It can also lead to heart disease and increased blood pressure if left untreated, meaning it is best to pick up the disease at as early a stage as possible. The condition is easily manageable and there are many options for treatment.

We recommend you discuss with our vets whether or not your pet would benefit from a screening blood test. Examples of when we might recommend blood tests would be for animals that are more senior in age, on long-term medication that has potential to affect organ function, or for an animal that has unexpectedly lost weight.

There are limitations to blood tests, and it should be noted that not all health problems can be detected with these tests. In some instances, if abnormalities are flagged up on the screening blood test, our vets may recommend further tests, such as tests on urine if kidney disease is suspected, to gain more information.
