Our cat has patches or fur missing. Can it be a flea allergy?

Flea allergy can definitely result in the loss of clumps of hair and if that’s the case, then using a reliable flea control product should see the hair start to grow back. However there are a number of other causes of hair loss. Food allergy is one, fungal skin infections is another. Some cats pull their hair out for psychological reasons. This means that if you don’t get any satisfaction from flea treatments, you will need to work out what’s causing the hair loss. Your vet is your ally in this. They’ll run some tests including combing the fur, doing a skin scraping, checking for fungi possibly with a Wood’s lamp or a culture, and perhaps they’ll need to even do a skin biopsy. It sounds like a lot of work but it’s pointless treating your puss unless you know exactly what is causing the problem. | 01.13.16 @ 12:53
