New baby kitten. Her name is Zena. Still on the same diet from the breeder, but having very runny dark brown “milkshake consistency” diarrhea. Still very playful, with good eat and sleep pattern. Has been leaving puddles under our bed, but also uses her litter box. I honestly think that she cannot make it there in time. Last week had her vet check. I don’t think its bacterial, but need some advice. I have her quarantined in a pet pen with a small litter box. We have no other animals. Any advice?
