Hi, before I take my cat in I was just wondering if anyone has ever had this problem with your cat, On Thursday he was limping on his right leg, Hes 15 years old I thought he may have fell but i saw nothing swollen. yesterday still limping and this morning i felt down his leg and felt a little crusty fur. This afternoon I felt it and can feel a little bump and looked but don't see anything. It is right where he has whiskers coming out of his leg, maybe in grown hair, infection? hard to say. Just thought I would see if anyone ever had this problem. I will be taking him in if not better in the morning, Thanks for any reply's....
