I tend to be conservative with things like this – I will put a dog with a sore limb on crate rest for a week to see if it resolves. If it doesn’t, we head to the vet. This means on leash when in the yard for toilet, no jumping in the car, no jumping on furniture. Just crate or on a cushy bed on the floor.
Things to do: check paw pads, check nails (most people keep dog nails WAY too long, so if you can hear them clicking, it’s time for a nail trim…and then do them twice a week until they’re short, and weekly to maintain). I also move the limb and gently massage to see if there’s any sort of soft tissue soreness.
hello,
I’m sorry to hear about your cat. But I cannot provide much assistance based on what you’ve provided here. Certainly things like infection , trauma and other diseases might cause this. I think the vet needs to be consulted again.
If needed go ask for a second opinion from another vet,, maybe even a cat specialist
sincerely
