First confirm with vet if the kitten has worms. If not, my home remedy is to use a little bit of pure 100% pumpkin paste. The one without sugar, to the food. It will settle the stomach and fix the diarrhea issue fast.Hi! Is it okay to give anti-diarrheal medicine (kaolin/pectin) to a kitten on the same day as he was dewormed? How soon can I give him the anti-diarrhea medicine after I gave him the dewormer?
