So, a little over a week ago my lil' buddy (11 months old) went into hiding for a day or so. When i finally found him and lured him out, I saw him limping horribly bad on his back left leg. After a few minutes, he was okay and started walking normally and playing with my other kitten (also 11 months old). The next day, he started limping again only this time, i started noting that it was when he was landing from a jump. So I kept him on the ground for the rest of the day pretty much. Then I noticed it was bad when he got up from laying on his stomach. I made a list of my notes of when it happened, and took it and him to the vet. So, to make me a liar, when he was let out of his kennel, he jumps off the exam counter and starts running around. Then tried getting under the table, then jumped back onto the counter, walked around, then jumped off again, with ZERO effects. When he jumped back up again is when his knee got weak. The vet then checked out his legs and said she's 99% sure it's a luxating patella, and its very rare in cats and it could have been hereditary. I wouldn't know, as they were both strays. Because he's still growing, so she suggested that since he's not in a lot of pain to wait at least 6-8 months until he finishes growing and it could fix itself, or if it gets worse, they can do surgery on him then, or ASAP if we wish. I hate seeing him injured like this, but he'll play for hours on end without an issue, and then he'll have problems again. When I just came home an hour ago, he was in his sleeping chair, went to the bathroom and came out and jumped up on the window ledge. then on the computer desk, so I took him down so he didn't jump down. He's still very playful and happy. Does anyone know how much (on average) this costs, or recovery time or the success rate? All I know, is I'll likely have to crate him for at least a month if and when he has the surgery.
