I live in a rural area down the road from a church. As with most churches, people abandon their animals frequently. Due to this I have feral cats that showed up and started living in the barn. All the animal shelters close are usually full, and since feral cats are definitely not in demand they're put down for the room. I currently have 2 feral cats and one 1/2 Siamese kitten. Both feral cats attack their right ear to the point where it's constantly bleeding. The kitten is not having problems with it's ear. The feral cats are related. I thought perhaps it was ear mites, and it was hell getting those ear drops in their ears. No improvement. Could it be an allergy?
