Kittens that have been fed a lot of milk from their mothers produce large amounts of milk in their feces. This is normal and can be seen with any litter or combination of kittens. In some cases, the amount may be significant enough to cause concern. The most common symptom associated with this condition is severe diarrhea. If you observe stool in your kitten’s litter box frequently, take it to the veterinarian immediately for a checkup!
