Why Is My Cat Losing Weight In Hindquarters?

Cats will lose weight from their hindquarters when they’re not eating well, aging, have cancer, have thyroid troubles, or are dealing with gastrointestinal issues. It’s best to visit the vet and get a complete report on what is going on with the cat.

Do not ignore this symptom as it is often a sign of what’s going on inside the cat’s body. You will want to make adjustments as soon as possible.

Reasons A Cat Is Losing Weight In Hindquarters

1. Thyroid Issues

This is one of the most common reasons for a cat losing weight.

When a cat is dealing with an overactive thyroid, it’s easy for it to start shedding weight. The body’s hormones are all over the place and this is not good for its ability to maintain weight.

Some cats will lose this weight gradually while others are going to see a sudden onset of weight loss that is not good for the body.

It’s important to keep tabs on these thyroid issues to make sure they are under control as time goes on.

2. Cancer

This is one term you are not going to want to hear when it comes to a cat.

You will want to assume there is something else wrong with the cat and it is quite likely there is another underlying issue that is causing the weight loss in a cat.

However, it is possible for cancer to lead to this type of symptom too.

The best option is to focus on visiting the vet and getting a complete checkup done on the cat’s body to see what’s happening and how it can be treated moving forward.

3. Not Eating Well

If a cat is not eating well, this is a simple explanation for it losing weight.

When cats lose weight, it is also a sign they are not getting enough food. If they are getting enough food then they might be throwing it up, which means it is not being digested properly.

You have to keep tabs on the cat’s diet.

If something has changed, this might be the reason the cat is not doing as well as it should.

4. Aging

It is important to note that sometimes the main issue has more to do with the cat’s aging. If a cat is getting older then it is going to start facing issues such as this one.

It is going to deal with fatigue and it is not going to eat as well as it used to.

These are common signs of issues with the cat’s body and aging can be a catalyst.

5. Gastrointestinal Disease

This is a condition where the body does not digest food properly, which can lead to an assortment of issues including weight loss.

You will want to get a complete checkup done to see what is happening with the cat to ensure this is taken care of as soon as possible.

It is possible the cat is dealing with parasites, which will cause it to have intestinal issues.
