Why is my kitten's white fur pink after Advantage flea treatment?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 2 months and 9 days old | 1lb

I've just used advantage flea treatment on my 12 week old kitten and his white fur is turning pink, is this a reason to be worried?

As long as Sushi's behavior is normal and the only sign you are seeing is the change in color of the fur I wouldn't worry too much. I would consider changing to a different formulation of flea control, like a collar or oral (i.e. Seresto, Comfortis). If you continue with topical medication you want to make sure that you are getting the medication on the skin only. I know this can be difficult because there is so much in those vials. You can part the hair a little further up her neck toward her head to give you more working room.
