Why are my cat's hind legs weak and getting worse despite vet care?

Updated on September 23rd, 2025

Pet's info: Cat | Cornish Rex | Female | spayed | 4 years and 9 months old | 4.5 lbs

4 weeks ago Topsy's (4, indoor cat) hind legs started to weaken. Took her to the vet, x-ray, abdominal ultrasound negative, no temperature. Vet said probable trauma and gave painkiller and anti-inflammatory meds. Gave injection and meds for 5 days. No use, condition deteriorated. He took blood test and gave another painkiller. Condition is worse, she can hardly use hind legs. Blood test shows no major problems (cannot attach as in docx). Take her to MRI today. Any idea for cause? Thanks!

It sounds like she has been treated very well so far but it I a complex case and indeed mri results should tell more as to whether there is a physical cause resulting in nerve compression. If negative, muscle weakness would be a concern which can be difficult to diagnose, muscle biopsy may also be cons

Why is my cat's front leg weak, has fever, and a painful neck?

That sounds like a really tough case. You may need to talk to your vet about advanced diagnostics such as MRI or CT scan, or a referral to a specialist. Has your vet done blood cultures? Checked fungal titers? Tick-transmitted diseases? You may also discuss supportive therapies with your vet, such as cold laser therapy or medical acupuncture.

My cat's hind legs are weak and he can't walk. What should I do?

I’m thinking that Mellow may be anemic, or have a low red blood cell count. If this is the case then it could take awhile to improve depending on the cause. It’s also possible that there is a neurologic problem. I would recommend rechecking with your vet to see if there is more testing that they might recommend.

My cat's back legs are weak, he walks drunk. Why are symptoms back?

Ray could have a problem with his hips and/or back. Given that he is returning to the same symptoms, I think further testing is needed. I'd make an appointment to take him back into the vet, and I would discuss x-rays as a next step. Best of luck.

My cat's legs are weak, she trembles and twitches. What's wrong?

I would be most concerned either a neurologic issue, such as a slipped disc pushing on her spine, or a blood clot lodged in the blood supply for her rear end (called Feline Saddle Thrombosis). I would recommend taking her to a vet ASAP to further evaluation.

My pet's front leg suddenly weak, vets can't find cause. What now?

Poor Toto. This sounds like it may be a neurological issue causing her immobility in her front leg, especially of all her preliminary testing came back normal. At this point I would highly recommend asking your vet for a referral to a neurologist, who can run more advanced testing (I.e. MRI, CT scan, etc) to diagnose her problem and then explore her treatment options.

Why is my cat losing muscle in her hind legs and what can I do?

Poor Princess! It's important to determine why this is happening in order to be able to treat it effectively. Muscle atrophy in the rear legs can occur due to arthritis, neurologic disease, an injury of some kind, or a metabolic disorder such as diabetes or hyperthyroidism. I would recommend taking Princess to the vet for an exam - he/she can do x-rays, blood work, or other testing if needed to help determine what is causing the muscle loss. Many of these issues are treatable once a diagnosis is made.

My 19-year-old cat is wobbling and dragging her leg. What's wrong?

Yes, you need to take Katie to the veterinarian. Weakness in the hind limbs can indicate many things ranging from hyperthyroidism to a spinal issue. A physical exam, blood work and potentially x-rays are needed for the correct diagnosis and treatment. Certain conditions, if caught early, are highly treatable. I hope this helps and please feel free to post any additional questions.
