My cat threw up after flea treatment. When should I see a vet?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 11 months and 7 days old | 9 lbs

My cat has fleas so I gave her frontline last week and I sprayed my house with flea spray and she has thrown up a few times which is unusual for her but she plays right after as if nothing happened. At what point should I take her to get checked out? Thank you!

If the vomiting becomes a regular thing at least 3 times a week, you should take her to the vet in order to get it checked. it could be the flea spray that you used for the house, it's not likely to be the frontline though. it could also be something totally unrelated and just a coincidence.
