Some of you have probably read my posts about feeding my neighbors' elderly cat. That's Blackie. Well, now another neighbors' cat has been coming to our house. It's cold, and she has been sleeping in the doghouse on our back porch. DH felt sorry for her and he fed her. Then he noticed that she had a number of knots on her neck around her flea collar. I checked and it is horrible. Her neck and head are covered in bumps. We figured the collar was either too tight and irritating her skin or she was allergic to it. We've never put a flea collar on a cat, so we really don't know much about them. Anyway, we removed the collar and she seemed instantly happier. I hope her skin will heal now that the collar is gone. They are not open sores, just rather large and numerous bumps.
