I filled Willow's water bottle with fresh water this morning at 7 a.m. I was curious to know how much he drank in a day, so I measured exactly 24 oz. It is now 6:45 p.m. and he hasn't drunk ANYTHING! The water line hasn't moved and I'm wondering if this is a cause for concern?

He also didn't poop/pee at all, until after I came home from work. Then it was WATCH OUT! all over the place. Is this something I should be concerned about too?

Help!! This is all so new!
