GOOD NEWS!!! Hubby and I checked on her just now, and there is a small amount of feces in the litterbox!! Not a large amount, maybe the size of my thumb, but I'm pretty sure it isn't something that just "fell out" on its own, you know?!

GO EMMA!!!!

EDIT: Yes, I am learning about manual expression BUT have not physically done it on any animal yet... I was going to talk with my clin med instructor tomorrow and ask if maybe she'll help me during lunch or something and show me how to do it. She's a wonderful instructor -- today she let us microchip all the kitties, and my class got to do it -- its the first time I've used a needle on an animal before and I was able to microchip my kitten Shelly... it was so cool!
