A few days ago, my very energetic 5 month old cat, slept all day. When I tried to play with him, he just fell asleep. The next morning, I grabbed him and he yelped. After that, he limps. I took him to the vet and the vet gave me pain medication and said he didn't think it was broken. He said he didn't know why he slept the day before. He said he had barely a fever and it was nothing to worry about. After three days, he is still limping pretty bad. He won't let me move his leg. I checked all his paws and foot. He does not care if I touch his foot. He gets really upset when I push foot toward his body. If I move his hip or knee, he cries. When he limps, he barely touches the ground. He doesn't mind laying on the leg but will not use the limb. His leg isn't worse after 4 days, it just isn't improving. He is still eating but not eating as much as he usually does. Does anyone have ideas what is wrong? I am taking him to the vet tomorrow but I am so worried about my kitten.
