Why does my cat’s hind legs fail

Why do my cat’s hind legs fail? The truth is that even wondering that is very worrying, because it means that something is wrong with your best furry friend and that he needs help as soon as possible.

With this in mind, we are going to tell you what the possible causes and their treatment are so that, in this way, you know how to help your cat.

What are the causes?

Seeing your cat with walking problems is not pleasant at all. When he comes to this situation, he spends much of the day lying in a corner, listless. To help you improve, the first thing to do is to know the cause of your condition:

Hypertrophic cardiomyopathy

It occurs when the heart muscle thickens , thus generating cardiovascular problems. So when various parts of the body, including the hind legs and tail, stop receiving enough blood, they begin to weaken.


If the cat has high blood sugar, the potassium level drops because it urinates more frequently. These drops in potassium cause neuropathies that can lead to walking problems .

Hip dysplasia

Although it is more common in dogs, hip dysplasia can also be suffered by cats; although in felines it is usually hereditary. It occurs when the bones of the hip and femur do not develop properly , causing pain, lameness in the hind legs, problems running or jumping, and crunching.

Chronic constipation

Chronic constipation caused primarily by kidney failure can lead to symptoms such as wobbling of the hind legs and difficulty walking well . In addition, others tend to occur, such as loss of appetite and / or weight and vomiting.


It is a blood clot that has stayed in some part of the body . If it occurs on the rear, the blood will not reach its feet well, so that they will become cold and with little mobility.

Other causes

We have seen the most common, but there are others that we cannot forget :

  • Cancer
  • Accident fractures
  • Leukemia
  • FIV, or feline immunodeficiency virus
  • PIF, or feline infectious peritonitis

What to do to help you?


Of course, take him to the vet . Once there, he will give you a physical exam and may order an X-ray or other imaging tests to find out exactly what is wrong with you.

Then, they will proceed to give you medications that will relieve (or cure, depending on the case) the symptoms. If what you have is a fracture, you could choose to have surgery to fix it, and bandage the leg.

And, in addition, at home you have to give him a lot of love , make sure that he eats and drinks well, and that he feels comfortable.
