How to tell if my cat is losing weight?

It’s not always easy to detect weight loss in pets, especially if they are hairy or overweight. That’s why you need to schedule regular wellness exams and examine them physically.

To check your felines’ weight status, you need to stand over them and look at their frame. Ideally, there should be a slight dip at the waist. If the dip is very noticeable, then your cat’s weight has dropped badly. Also, you can use a digital cat scale for weighing cats perfectly.

Reasons that your cat is losing weight

There are many reasons why your cat may be losing weight. Moreover, understanding your pet plays a significant role here. This is because sometimes, your pet is losing weight just because it isn’t eating as well as it should. So, paying attention to your cat goes a long way in helping you discover the reason for its weight loss:

Change in Season

Cats often lose weight in the summer. So, if your cat is losing weight in the summer, don’t panic.

The mild weather in summer and spring encourages pets to move around more often and engage in more activities than they would in other seasons.

The warmth in the atmosphere also makes them more inclined to drink water, as it often leads to a loss of appetite. Therefore, if your cats reach for water instead of their meals, you’ll know that they’re losing their appetite.


If your pet’s diet lacks the necessary nutrition for its age, it will be underfed, underweight, or worse. As a pet owner, you should only give age-appropriate meals to your pets.

The VCA Hospital explains that senior cats need a higher protein diet to prevent diabetes. However, younger cats can maintain variety in their nutrition. Besides, studies have shown that wet food can cause weight loss in cats due to its low energy density.

Stress or Change in Environment

Generally, felines are sensitive to their environment, and any change to an unfamiliar one would affect them. The result is that they have different responses to changes and can take a while to adapt.

They also can become anxious or stressed if the environment is unfamiliar or unfriendly. Thus, suppose your feline friends are uneasy in their new home and become underweight. In that case, it’s because they haven’t adjusted to the new environment.


The disease is a common cause of weight loss in senior cats. They often have diseases that make eating or swallowing food difficult. It will prevent them from eating as much as they should.

Cats are prone to medical conditions like kidney or liver disorders, gastrointestinal problems, diabetes, cancer, or dental diseases.

If your cats have any of these, it’s normal for them to lose weight or be unable to eat as they should. Therefore, you should regularly get your cats examined if you notice signs of discomfort, nausea, shortness of breath, or less activity.

You must also stay watchful, be consistent with their medication, if any, and report to your veterinarian when you notice sudden changes.
