I rescued a newborn kitten. Found her outside surrounded by her dead brothers and sisters. She was crying. Ive had her for 3 days now. She is brand new. Her eyes arent even opened yet. She cries a lot and feeds hungrily. She is already climbing up the towel in her box. She seems strong. She is feeding well and urinating a lot. I have followed all instructions to get her to poo and she has only gone once. She went 2 days ago and hasnt gone since. She is still drinking the replacement milk I give her eagerly. I have gently rubbed her tush with a warm, wet paper towel. What else can I do to get her to go? How often should newborns poo? Should I be very worried? She's already been to a vet and everything checked out ok.
