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

This is an emergency, as your cat could be suffering from a riding thrombus, which is a blood clot that keeps blood flowing from the aorta into the femoral arteries. This is a very painful and life threatening condition. She could also have been a victim of a traffic accident hurting her spinal cord. Please take her to a veterinarian or an emergency room right away. The vet will want to do radiographs and a blood test and your kitty will need treatment depending on the diagnosis today.

Thanks for using Petco Pet Education Center, formerly Petcoach! These are general signs that can be seen with a lot of conditions. It could be due to a neurologic condition or perhaps an orthopedic condition causing some kind of pain or discomfort. If this continues, I recommend you have him evaluated by a veterinarian for further assessment and treatment. They would be able to start with a good physical examination and possibly diagnostics to get to the bottom of this so that therapy if any can be started. Have a great day!

If your cat is suddenly very weak, disoriented and unable to walk normally it is best to seek veterinary care at your vet or an ER clinic immediately. It is possible there is an injury, neruologic or muscular issue, illness, or other underlying problem that should be seen ASAP especially if it is causing disorientation and weakness.

Poor Bady! She needs to see the veterinarian today as she is very sick. There are several different conditions that will look like this including diabetic ketoacidosis, cancer, stroke, hyperthyroidism, infection, severe kidney disease or electrolyte in balance. These conditions all require treatment and are best addressed early on for the best potential outcome. The doctor will perform a physical exam and some bloodwork which will help to figure out the cause. Best of luck and please feel free to post any additional questions.

Difficulty walking could be a sign of neurologic disease, and infection would be a concern for a cat Fluff's age. Some parasites like toxoplasmosis can cause neurologic disease, as can viruses like the feline immunodeficiency virus. Difficulty walking could also be related to trauma but this might be more obvious on an exam. If the labs are not conclusive, a referral to a neurology specialist might be recommended as sometimes advanced diagnostics like an MRI and/or spinal tap are necessary for a diagnosis. If she continues to eat and drink normally and does not seem painful I'd wait for test results to come back and discuss the next step with your veterinarian.

You should take him to to the vet urgently, it is an emergency, it could be nerve damage or a clot in his blood vessels in the legs, either way you have to act fast otherwise the damage will likely be permanent, take him right away to the closest vet.
