Smokey is a 17.5 year old male cat. Last week he was eating and he looked like he was having trouble standing. We took him yo the vet and they found a big infection on his front leg. It exploded with two teaspoons of pus ran out. The vet checked his blood and all looked pretty good. Just dehydrated and a bit of a low temp. He got meds for his leg and we took him home. He had been eating like a horse only if I hold him up. He stretches all four legs but really can't stand on them. Not sure what's going one...please help.
