Lizzie you've got several things going on at the same time so it's going to be hard to figure out exactly what is causing it. I'm only guessing here but Rosco and Abigail don't like the Kitten Chow. They eat like pigs when they get the big kitties chow. It may be that Sophie is really fond of the adult food and is gorging herself on it. If that is what is going on then she should soon adjust to the food always being available. On the other hand she may be having a problem with the food change. I would stick with one type of food only and see if things ease up. If she continues you may have to go to some type of special food but I would give it a little time first.

Don't panic and don't worry too much. Just keep an eye on her and Tito. If you don't see any weight loss and they are drinking plenty of water and eating I would wait a little while before I paniced. We all understand the puke thing! Leroy deposited one huge puke pile right in the seat of my chair last night while I went to the bathroom!!! YUK!

If I ever win the lottery I'm going to open a carpet store with every puke stain color I can come up with!!
