Why is my cat struggling to stand and move her back legs, and shaking?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 4 years old | 5.8 lbs

My cat has been experiencing tremor type shakes in her back legs for a long time, since she was a kitten. It was mostly when she would lay still or just be kneading something soft. Today j can home and she was not acting right, she acts like it hurts to stand or move her back legs. Shes still eating a little bit here and there, and she does stand up occasionally but she seems to just want to lay down most often. What could this be?

There could be a problem with Charlene's back or hips. It's very concerning that it appears it hurts her to stand. Rest her tonight, and have her seen by a vet in the morning if she is still acting this way.

    Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm very sorry to hear that Kitty is paralyzed in her hind legs. I would be worried about some type of trauma, such as being hit by a car or falling from a tall height. It is also possible for cats to develop a blood clot that gets lodged at the bifurcation of the two major arteries that go to the back legs (called a saddle thrombus), and this cuts off the blood supply to these legs, causing them to slowly die. Since she meows when you try to stand her up, I am really worried that she is quite painful, and recommend that she be seen by a veterinarian as soon as possible. Your vet can examine her and try to determine if there is a treatment for her. Alternatively, if she is very painful and suffering, your vet may recommend humane euthanasia. Again I'm sorry for Kitty, and I hope this information is helpful.
