My kitten has unequal pupils after flea shampoo. What's wrong?

Updated on September 23rd, 2025

Pet's info: Cat | Scottish Fold | Female | unspayed

Hello, I just gave my three month old kitten a bath and used ticks and flees shampoo. I made sure it didnt go in her eye. But when i was done one pupil was bigger than the other. I am unable to go to the vet since my country is in lockdown. Please help.

Most of those flea/tick products are not labeled or recommended for kittens and can be toxic. Even some labeled for cats should not be used. I suggest you bathe her again with regular shampoo or baby shampoo to remove any of the other shampoo's residue from her. Rinse her eyes out with saline solution or just plain water. Those flea/tick shampoos can cause these types of side effects (unequal pupils and other neurological problems). The pupil will probably not go back to normal for a few days to a week. There is nothing else you can do at home.
