Pet's info: Cat | Domestic Shorthair | Female | unspayed | 8 lbs
My cats were treated at the vet today with Revolution. The vet used it for ear mites. She didn’t tell me it was for fleas, ticks, and heart worm too. My pregnant female has already been treat a week ago with advantage multi and my boy was treated with sentry. Now I’m worried they will both have severe reactions. I need advice on what to do and what to expect.

I would not worry about severe reactions as selamectin (Revolution) is an avermectin and can be used after Sentry and Advantage multi without a problem. Avermectins are a different class of acaricide and therefore there will be no overdose when used with the others. Both your kitties should be ok and there should be no adverse reaction re the kittens either.
