My adult cat has moist, blisters and/or injuries on his left front leg only. The places started at his foot and are climbing up the leg. All hair is gone from these spots. He does not seem to lick or scratch this area often.
He also does not have fleas or ticks to my knowledge. I have checked him thoroughly (and he is white so it would be easy to see).. Help!!!
This could be a eosionphilic plaque. It can be caused by an allergy of some sort. This should be checked by your vet and treated b/c they tend to get worse.
