Health Concerns Related to Cheristin, Comfortis, Trifexis

Thanks for posting this. My cat had quite a reaction--vomiting, not eating, totally lethargic, crazy blood values, after his flea meds. Eventually wound up with a feeding tube for three weeks. I'm lucky he's still with us. Definitely won't do that again. He's been fine since.

My pug vomits every time I give him his monthly dose of Trifexis.
