Well I hve a cat she is almost 3 years old about 2 months ago she got some bumps on he neck and she's had it before and I thought maybe fleas so I put medicine on her but that didn't do anything so I changed the food and that seemed to work a little bit but now the bumps go on to her back and she had a bald spot on the back of her tail she hasn't been acting any different she is very energetic and love to be pet and doesn't seem to be scratching and they don't seem painful she is an indoor cat and I don't think it has the do with bugs... any ideas other than the vet because I will be making a trip with her
