My new kitten has diarrhea but is playful. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 3 lbs

I adopted two kittens yesterday who were being fostered in an apartment, eating Purina One kitten formula. One of the kittens is experiencing diarrhea that occurred twice outside the litter box and once inside. I fed them that same Purina One last night and this morning, when it occurred twice, and then fed them a can of N&D wet food, when it occurred once more in the litter box. She seems otherwise fine in play behavior and energy levels.

The most likely scenario is that she has intestinal parasites/worms. Very common in kittens even if they have already had a dose of deworming. I do not think it’s from the food. I suggest you get both kittens to your veterinarian for a exam and a fecal test.
