SOOOOO, I think I know why he threw-up. I found a Ferret last night and took him in cuz I couldn't stand seeing him outside all alone. Well, I got some cat food from the neighbor to feed him, and I think he kicked some out of the cage and Epsilon ate it. There was probably just enough kibble on the ground this morning to upset him and he got to it. My husband woke up first this morning and was the one to let the dogs out, and of course he wasn't paying attention. But that's my theory.
