It's so funny how bunny parents can get so excited when there's poop in the litterbox! Caspian passed some pretty small pellets, but it's a start. His butt is very wet, so he's peeing, too. He's fighting me more when I syringe feed him (yay!), and he's up on the shelf in his house. He's grooming, itching ears, and getting mad when I blow on his nose.
I'm hoping I don't have to take him to work with me tomorrow. Though I'd love to have him there (despite not having a good spot for him there - just moved cubes last week), I don't want to have to haul his heavy butt for the walk from and to the train station (about a mile total).
