Is my kitten safe near a cat who had a bad flea treatment reaction?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | 15 lbs

I used hartz ultra guard on my adult cat and he had a bad reaction to it. We gave him a bath with dawn and now he is back to his normal self and we're keeping a close eye on him. Is it safe for my 5 week old kitten to be around him? I don't want her to get sick.
