Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Blacky! He is adorable! Blacky looks to be a kitten. Causes of diarrhea in kittens are: intestinal parasites, viral, bacterial or protozoal infections, she ate something gross that is upsetting her stomach, food allergy/intolerance, reaction to a food change, new treat or people food. When it comes to cat diarrhea, if it doesn't bet better in 1-2 days I recommend a vet exam. I would bring a stool sample to have it tested for worms. The vet can prescribe safe medications and a special intestinal diet to help her get better faster. I wish you and Blacky the best!
