Last week my aunt started noticing blood like stuff on her cats chin, she got it off.. and the next day it reappeared.. and she also smelled a horrible smell so she looked in his mouth and his teeth were like rotten.. this is a fairly young cat that eats only hard cat food.. she took him to the vet.. and the vet said that he was allergic to the enamel on his teeth.. anyone ever heard of that?? So, they had to pull several of his teeth. Well, a few days ago he started puking and couldn't hold anything in. So.. back to the vet. They did an xray and found out that his colon was severely impacted.. we guessed from the antibiotics he was on from his teeth. They kept him overnight.. and he started getting even sicker. 3 days, several tests, and lots of money later.. they decided today that he had been bitten by a flea and had a parasite in his blood. I don't think it was worms.. they just said one flea can carry the parasite. Even though she had him on frontline. I guess its a pretty bad parasite. Anyone know any information about it? She didn't say much else.
