Possible Reasons Behind Weight Loss in Cats

 Anorexia or weight loss in cats is of two types: primary and secondary.

Primary anorexia and weight loss are linked to the parts of the brain connected to the appetite and satiety centers.

Secondary anorexia may be linked to causes such as:

A) Infections or diseases

Your cat might refuse to eat if it is in pain.

Sometimes, diseases of the pharynx or mouth (broken or loose teeth, injuries) can cause difficulty in swallowing.

Gastrointestinal/metabolic/neurological disorders can also be a cause of poor appetite.

Kittens and adult cats with IBS may not gain weight because of poor nutrient absorption.

Then there are some serious causes. Neoplasia (benign or malignant growth) can lead to lack of appetite and subsequent weight loss.

Treating the underlying condition can improve your cat’s appetite and lead to healthy weight gain over time.

B) Lack of diet palatability

Cat food can get spoilt.

Wet or canned food left outside in warm weather can develop a strong smell along with bacterial contamination.

Since cats are picky, such strong flavors and scents can turn them off food.

Some foods simply have a strong odor which your cat may not like.

C) Strong dietary preferences

Many cats are extremely picky and their pickiness increases with age.

Switching to a high calorie wet cat food or high calorie dry cat food can help increase nutrient absorption- so the good stuff goes to work in your pets even if it eats less.

You simply might have to try different flavors to find something that your pet loves.

Food toppings and pastes or gels in the form of high calorie supplement for cats can also help.

D) Environmental stress

Cats are very sensitive to changes in their environment.

Your cat might have suddenly become anxious or frightened owing to noises, changes in its routine, death of a fellow cat, moving to a new place, or even bringing home another pet (dog or cat).

The perceived competition could lead to weight loss in your pet.

How to Assess the Cause of Weight Loss in Your Cat

It is very important to rule out diseases if your pet is not gaining weight. This will help you decide the next course of action.

Here are some questions to consider in order to arrive at a conclusion:

• Is my pet showing an interest in food?
• Is s/he attempting but failing to prehend the food? – (This means that your cat has appetite but is unable or unwilling to eat it?)
• What and how much is your cat eating? Is it more or less than usual? If you have multiple cats, it can be difficult to assess how much one cat is eating.
• Have you recently changed your fur-baby’s food? If it is a lower calorie food, then that could amount in the weight loss.
• Has your cat’s environment changed: a new house, a baby, or new cat?
• Do you keep food accessible to your pet at all times? Where do you feed your cat?
• Is your cat scared or reluctant to approach food? Is someone scaring your baby? (A child, dog, or dominant cat?)
• Have you tried feeding/offering other foods? What was the result?

These questions can help you determine whether switching to the best high calorie wet cat food or high calorie dry cat food can help?

How to Choose High Calorie Cat Food for Weight Gain

Below are some factors to consider when selecting high-calorie diets for your kitty:

1) High in proteins and good fats

Select a diet that is higher in calories.

Do make sure that a majority of the calories comes from high-quality proteins and health fats.

Animal nutritionists recommend feeding adult cats at least 30% proteins along with vitamins and minerals.

2) Easy to digest and free from allergens

Many cats are allergic to certain ingredients in cat food.

Typically, the causes of allergy in cats include wheat, soy, gluten, dairy, and most grains. (Note that not all cats are allergic to these ingredients and what suits one may not necessarily suit another).

Some trial and error can help you find out your cat’s preferences.

Whichever food you choose, make sure it agrees with your pet’s system.

You can select foods without grains, wheat, and soy and those containing a high-quality poultry (chicken, turkey) or sea food(fish) as its first ingredient.

Avoid foods with preservatives, meals, by-products, colors, dyes, fragrances, and fillers.

3) Suits your lifestyle

If you are away at work all day, you might find it more convenient to leave dry cat food out for your pet as opposed to high calorie canned cat food for weight gain. This is because, dry cat food is less prone to spoilage.

Your cat can have easy access to the dry food and eat it as and when it gets hungry.

4) Your cat loves it

Finally: the best high calorie cat food is the one that your pet approves of.

Cats are picky eaters and can turn up their noses even at gourmet foods. So, make sure to try out some variety. This way, your cat can decide on a flavor it likes best.

Tips for Weight Gain in Skinny Cats

In case you keep multiple cats, feed your skinnier pet separately to ensure that s/he gets its fill.

Try and supervise your pet when it eats.

D) Switch to dry food (or vice-a-versa)

If your cat has been eating wet or canned food, then switch to high calorie dry cat food for weight gain.

Conversely, switch to wet pate or canned food if you have been feeding it dry food.

Warming up your pet’s food can help enhance its taste and palatability. This especially works for high calorie wet cat food for weight gain.
