We live in a rural area, a few cats nearby but in the middle of open fields. One of our cats has twice had a major scrape on the scruff of his neck that has taken all the fur out and left the skin bare and exposed. On one occasion, it became infected and we went to the vet for antibiotics. The vet and i couldn't work out what caused it. Now our other cat has an identical bare strip on her side - about 2cm wide and 4cm long. I'm worried that someone is doing something to them deliberately- can anyone come up with a more palatable alternative? I'll try and post a pic
