Ollie is now 12 days old and has been doing great. Eating well, eyes started to open, putting on 1/2 oz. a day, and learning to groom after meals. His last bowel movement was Sunday morning. I know they don't go everyday, but now we are on day 3. Is this normal ? I have been using cottonballs to stimulate him. He pees alot, but no poop. I am getting concerned. Any advise?
