Can I split one Revolution flea treatment dose between two cats?

Updated On September 23rd, 2025

If a vial of revolution flea treatment for cats is marked 60 mg 15.1 to 22 lbs can I use one treatment on two cats that are under that weight? Together their weight is about 17 pounds.

I'm afraid that this is not recommended - topical flea and heartworm medications like Revolution should always be used according to the label directions. Splitting a dose between two cats is not safe since there is no way to know if you're using the proper amount on each cat. I would recommend getting the correct size for your cats' weight and giving each of them a single correct dose.
