Are flea collars on outdoor kittens enough to protect my indoor cat?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 3 months and 14 days old | 2.8 lbs

We have three feral kittens about 4 months old living in our backyard. We have a feral kitten from the same litter that we rescued from near death and are raising indoors. He has kitten revolution on him. The feral kittens are vaccinated and neutered. We like to let Whitey out to play with them while we supervise as he is driving our 3 older cats crazy. My question is: will flea collars on the outdoor kittens reduce Whitey's exposure to fleas? The more expensive meds are out of the question.

Flea collars is a good idea for the feral kittens, but fleas do not live on the animal, they live in the environment. The problem is the outdoors where fleas live which can jump onto Whitey. He is protected from fleas with the Revolution, but potentially he could carry them into the home, causing the home to be infested with fleas. To keep your house from having fleas in it, I'd keep him indoors. Best of luck.
