Felix is hopping along on three legs. His sore paw does not seem to be improving despite antibiotics, anti-inflammatories and painkillers. He is confined to the house and spends some time looking for a way out. After his meds at breakfast time, however, he spends a long time sleeping. He uses his litter tray once a day. Such control! I’m worried about his paw. What is going on in there that we can’t see? He uses his left paw (the sore one) to play, but not so much for walking. Why is it not getting better? Will he end up three-legged?
