Pet's info: Cat | Mixed Breed | Male | neutered | 7 lbs
I put flea and tick topical treatment on my cat and it cased seizures, the seizures went away after a month, but now I noticed a swelling on his chest near his right arm a few days ago about the size of an egg, today I noticed it went down some and where he was laying there was a clear wet spot, so it must have drained some, what I would like to know is could it be a allergic reaction to the flea and tick treatment? or what could it be? I;m very concerned and haven't the money for a vet.
