My senior cat has hind leg weakness on Norvasc. Is it a side effect?

Oh no. Poor kitty. Blood pressure can be affected by either of these conditions, but is impossible to say for sure without getting her blood pressure checked. This is a tough one, because there are so many possible causes for her weakness and slow breathing, but I would have to assume that her underlying heart condition may be the culprit here. Saddle thrombus is also a big concern with cats that have underling heart disease, and can lead to sudden paralysis of the hindlegs, with vocalization (moaning). I know you don't trust the other vets in the area, but it may be worthwhile at least taking her in to see if her blood pressure is indeed the problem. Getting some bloodwork analysis on her may also be indicated, depending on her physical exam findings. We have to keep mind too, that unfortunately CHF patients can only be helped with medication for oh so long, because it does not cure the underlying problem. I hope that Brancinia is going to be ok, but its best to take her in immediately. Waiting for your preferred vet in this situation may be more detrimental to her overall wellbeing than taking her in to determine her current status. I wish you all the best with your furry friend. Take care.

I'm sorry to hear that this is going on with Virtue. My biggest concern would be that he has a developed a blood clot that has disturbed the blood flow to the back legs. This is unfortunately one of the common side effects of kidney disease and hypertension. I would recommend taking Virtue in to see your vet for a recheck as soon as possible. They will need to check his kidney values and see if they have worsened, check a blood pressure and may recommend starting Virtue on additional medication, such as aspirin, to help with the clots. There is a chance that this abnormal walking could be due to arthritis and aging. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

I'm so sorry Pico isn't doing well! There could be a couple of things causing this, including the gabapentin. As cats age, their efficiency at metabolizing gabapentin can wane, and this can lead to hind limb weakness. That may be why he's getting worse. I would take him into the vet first thing tomorrow to discuss lowering the dose, which may help with the increasing hindlimb weakness. You can also discuss if using another medication in combination with the gabapentin is ideal for Pico.

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.

A clot that causes limping is VERY painful. We do not expect cats that have thrown clots to recover without significant treatment. So, that certainly makes it less likely that Luna had a clot. However, I would strongly recommend having her examined to see what is going on. It certainly is not normal for a 6 year old cat to be limping. If Luna does not do well at the vet, maybe a house call vet would be a good option for her. I'm not sure if there is one in your area, but this might be a good place to look for one. http://www.homevets.org/Find_A_Mobile_Vet.html Good luck! I hope that was helpful and that Luna feels better soon. Thanks for using PetCoach.

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.

Poor Kosho! She could have accidentally injured her limb at night while you were asleep. She could have severely strained a ligament, torn a ligament, broken a bone, or potentially could have an osteosarcoma. An osteosarcoma is a tumor of the bone in cats, the most common bone tumor cats can get. It would cause sudden and severe lameness. Unfortunately, cancer is always a possibility in an old cat. I would take Kosho into the vet today for an exam. The vet can do a physical exam, routine blood tests, a urinalysis, and x-rays to determine what is causing her limp and how best to treat it. She will also need some pain medication as well. Do not give her any human pain medications. Many are toxic to cats and are fatal if given. Please take her into a vet now.
