I have a cat who is about 6 to 8 years old (probably older)who all of a sudden is having some trouble standing up and walking. He seems to be in pain when he wants to stand up or walk. The two front legs seems fine.It looks like it's his back legs that is causing him some pain. He is a very active cat but now he looked lame. I will take him to the vet tomorrow but in the meantime, can you give me some advice as to what seems to be causing this?
