9 week old kitten is sick after using revolution. She is lethargic, only eating & drinking a small amount. Cant get to the vet until Monday as we live in a very rural area. Please help.

Thank you, cat Nana

What is 'revolution'? Is this some kind of treatment ? A flea lotion ? 9 week old kitten should be subjected to any kind of chemical.

This is prescriptive from a vet. What do they say? Did you get this from a vet or passed on from someone else?

I googled revolution and found it is approved for puppies and kittens as young as six weeks old. Perhaps the kitten was already ill when the application was applied.
