Why are my 7-year-old cat's hind legs making cracking noises?

This could potentially be a sign of arthritis. Unfortunately there are no human pain medications you can give Garlic. Many human ones are toxic to cats and are fatal if given. I'd have him seen by a vet for this problem. The vet can prescribe safe pain medication if needed.

There may be some arthritis that could be age related or related to his old injuries. Ideally, he should be examined and possibly x-rayed by your veterinarian. If he is painful, your veterinarian may prescribe medication for pain management.

Most likely this is arthritis. If he isn't limping then this is aa good indicator that it isn't causing too much pain yet. You can try over the counter joint supplements like Cosequin to help replenish fluid in the joint and also to help slow down the progression of arthritis. If he develops pain or limping then it is best to have the limb radiographed to get a better idea of what is happening internally, and also to get a prescription for stronger medications to help with pain.

At his age, he likely has some arthritis. I suggest you get him started on a joint supplement. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=120626 Give it a good 4-6 weeks to see if it helps him. If not, then please post again and we'll see if we can give you some more suggestions.

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!

Thanks for using Petco Pet Education Center, formerly Petcoach! I am very suspicious of arthritis is Sassy based on what you describe. Arthritis is not unexpected - but also not "normal". I do recommend treatment to give her the best quality life she can have. See your vet to help rule out something more nefarious (because cancer and other things also can cause problems in older cats). Then have a discussion about safe medications and supplements for cats. Some of my favorites are adequan, duralactin, and gabapentin. Best of luck to you and Sassy!

it sounds like your kitty may be in pain. This could be from an injury, or arthritis. I suggest you take Felix to your veterinarian for an exam and possibly x-rays. If he has arthritis pain, your vet will likely prescribe meloxicam for him, which is an NASAID which reduces inflammation and pain.
