My little kitten Vega is 12-weeks old and went to the vet earlier today for his second round of vaccinations. He was also given Comfortis for flea treatment. Within about half an hour he threw it up and tremored a little. Since then he has been lethargic and weak and when I pick him up he cries out and meows in a very weak and agitated sigh. Fortunately he has been eating his meals but he has not been asking for them like he usually does and rather I provide it to him before he meows for it. I will call the vet in the morning once again but I read online of various people who gave their cats Comfortis and I have seen many side effects and bad effects including even deaths. I wanted to see if other people had a similar experience or advice? Thanks and hope all is well.

I have not used Comfortis; but, I have had kittens and cats who had reactions to vaccines (all vomited.)

Vaccines alone can cause lethargy and a temporary decreased appetite.

I would definitely call the vet in the morning (even just to report Vega's symptoms.) If his symptoms worsen, give a 24 hour emergency clinic a call.

I agree with Cat Pac k. You need to report this.

My cat has taken Comfortis and it was obvious it mDe him uncomfortable , though I don't remember it giving him seizures . I would be off my food too, the stuff stinks. But my kitty recovered ok. Yours probZbly will too

Ps my cat is half Siamese, and they do hVe kinda delicate reactions to shots and the like...and when my cat gets tired, he gets...trembly and non reactive, almost like a seizure . He always recovers though .

Wish you well. Me , I use Advantage (ix. ?) or Frontline now. Just my opinion but Comfortis was, imho, too strong.
