My cats lick Seresto collars. Will they get sick or be harmed?

Updated On September 23rd, 2025

Hi - I have two, bonded cats that clean each other often, and we just bought Seresto Flea and Tick Collars for both of them. Will they get sick if they happen to lick each other’s collar?

Hi there. No, this shouldn't be a problem. The Seresto collar is designed to slowly release medication over the entire 8-week period, and should not cause toxicity issues if it is accidentally licked.
