So of course after going for 38 hrs without pooping (the longest now), she and her brother took turns in the litterbox very early this morning and still throughout the morning. Poor Dave was up at 4-ish for a Bag pee, then again at 5-ish for a Noodle poop (a good one, too). Bag decided he needed to poop around 6-ish, then Noodle peed at 7-ish. She peed again at 820, 10-something, and around noon. They were all small pee trips, so now we are monitoring that. Goodness.
And not to be outdone, Bag - who had been sleeping all morning - pukes up his wet food in the bathroom. At least it was on the mat which is now in the washer.
They played with each other some, Noodle holding Bag's head down while she groomed him, and although both took some interest in the catnip, it didn't seem to make much of an effect. They've settled down slightly, although Bag is still waiting for food, thinking he is starving, I'm sure.
