What is a Healthy Weight for a Cat?

How would you know if your kitty needed to shed a few pounds, or pile on a bit of weight? Fat cats are very common, and you may not even realise that your cat is overweight, or thin. But, it is something to take seriously.

  • Domestic cats, in general, should weight around ten pounds, but this can vary depending on your cat’s build or breed. For example, according to the Association for Pet Obesity Prevention, a Siamese cat can weigh as little as five pounds, but a Maine Coon can be more than twenty pounds and beyond!

Your vet can tell you if your cat is under or overweight, but there are some signs which you can look out for as indicators.

  • Cats should have an hourglass figure when you look at them from above, they should not have a bulging stomach but, on the flip-side, you should be able to feel their ribs; this does not mean they are underweight!
  • Tip: Place both of your thumbs on your cat’s backbone and spread both of your hands across his rib-cage, you should be able to feel his ribs. It’s not always best practice to just look, because a cat’s coat makes a visual check difficult.
  • You should also be able to feel a cat’s spine when you rub your fingers along their back. However, this is where it gets difficult, because the spine shouldn’t be overly obvious.
  • Additionally, when you stand over your cat, you should be able to see its torso tuck in where its ribs finish, but an over-exaggerated or extreme tuck is a sure-sign of your cat being underweight, whereas fat cats may not have a tuck at all.

Don’t be freaked out if your cat has a curvy figure, though, it is not going to get heart disease by being a little overweight – there are plenty of bulky kitties roaming the streets!

  • Extreme feline obesity is rare, but it can be very dismal. Just like humans, extra weight puts an extra strain on cats and increases the risk of serious health problems such as diabetes, arthritis, heart disease and high blood pressure, to name a few.

Why is My Cat so Thin?

Your cat’s environment can affect weight loss, and your cat may start eating less or refusing to eat altogether if his environment isn’t suitable or disturbs him.

Not Getting Enough Sleep

Make sure mealtimes are quiet so that your kitty can eat uninterrupted, by people and other pets. Some cats can also develop anorexia, a refusal to eat, just like we humans can. This is usually due to stress or another psychological or behavioural disorder.

If your cat begins to lose weight drastically, or refuses to eat and not put on weight, you should pay your vet a visit to rule out an underlying issue such as disease.

Allergies or a Gastrointestinal

Your cat may also be suffering from allergies or a gastrointestinal issue which might cause him to lose weight. Sudden weight-loss might be attributable to allergies or a new intolerance. Long-term thinness may be caused by an infection.

Roundworm Infection

Roundworm, a common parasitic infection of the feline intestine, could be the rot cause of your cat’s slender figure. If your cat is well-known for bringing home rodents, it may well be that he has caught roundworm from one of his recent kills.

Older cats begin to show changes in weight more drastically than younger ones. Whilst some older cats plump up, others may slim down, too.

Constipation or Metabolism Changes

Elder cats may suffer from constipation or metabolism changes which could cause weight loss. A decreased sense of smell or problem with your cat’s mouth, such as a dental disease, may also be the culprit, as it will inhibit eating.

Each and every cat is unique, so it will take some careful watching and possibly a visit to the vet to figure out why your cat is thin.

How to Put Weight on a Cat

First of all, before you do anything, you should get to know your individual cat’s ideal weight and then produce a target weight. It is soooo easy to overstep the mark and turn who was a thin cat into a very fat cat, which comes with different health problems.

You should start with your cat’s diet. A cat’s gut is designed to process a high protein diet, and food source which contains a low proportion of protein is not optimal and may be hard for your cat to digest.

Consult with your vet about the right diet for your cat. Although many supermarket brands are palatable, they are made with the addition of flavourings and therefore their nutrition is less than ideal.

Raw food diets are high in water and nutrients, and can be a great alternative for your kitty. The best part about raw foods is you can make them at home – just ensure they are nutritionally complete!

Increase the amount you are feeding your cat!

Most cats opt to graze throughout the day, rather than gorge themselves all at once (though, there are certainly exceptions). Being mindful of this, feed your cat more than once, more frequently, rather than offering one single large meal. This is more aligned with your cat’s natural digestive process; he is more likely to finish multiple small bowls than a large one.

Food calorie content plays a major role here, and you should consider investing in a high calorie cat food. In general, wet canned food has a higher water content, so switching or introducing a dry kibble is a great move (which is why, above, most of the recommended foods were dry!) Remember, the lower the moisture content, the higher the calories.

You can also give your cat treats between meals. They are generally tasty and are extra calories for your kitty. Also, cats will rarely turn down a treat! Don’t over-do it, though, or your cat may refuse his next meal.

So, what now?

High calorie cat food is a great place to start if your cat is looking a little bit thin and dishevelled. Slowly move your cat off his current food and introduce a high calorie one, and watch for results. The extra calories should quickly pile on and you should notice a plumper, fuller figure.
