Thor was having some issues yesterday where it seemed like his body would shake (like a shudder) and he was losing some fur. Our vet said he might be allergic to flea bites. I gave him a good brushing yesterday and wiped him down with a cool wet rag to see if I could find any flea eggs but all I saw was what looked like dried blood.
Just to be on the safe side, we gave both of the cats a dose of Advantage to get rid of the fleas. Every time this happens, Thor goes positively crazy. He cries, tries to get comfortable and sounds like he's just miserable for the whole day after we applied it. Is the flea treatment hurting him?
I've tried to look some things up on the web about it, but all I get are pet pharma junk links. Any help you could provide would be much appreciated!
