With one chin it's always easier. In the cages with four, five or even six chins I SWEAR they dare each other to do things. "Hey, Lemon, go pee in the food, it makes her so mad...she'll yell but she won't do anything!" "Hey Pammie, eat everything but one crumb of eat pellet and throw it in the bowl! The last 12 years she has thought you have had a dental problem even though you never have and probably never will...hehehehehe."
I don't know if it is just my mental illness(es), but I think they are ganging up on me. One chin doesn't have anyone else to conspire with. I have the least mess in single chin cages. Jeeves, Simon and Boo don't have so much as a stray dropping in their food dishes.
