A very sweet, young adult, neutered male cat was presented by a Good Samaritan for evaluation. He had been found by the road. The Good Samaritan was unwilling to provide care for the cat so he was surrendered to the clinic. The cat was found to be extremely thin, body condition score 1/9, febrile at 103.9, depressed and mildly dehydrated. His right hind leg did not seem to work well and the thigh was severely swollen, warm to the touch and had multiple wounds present. Radiographs were taken of the leg and a severe fracture was confirmed. He was rehydrated and sedated to evaluate the swelling of the leg. See the video. Feline Leukemia and FIV tests were negative.
What is this and what is the best course of action for this kitty?
