Sometimes the two house toms get upset and vomit their food.
Jabberwock is especially easy for Spelunker to intimidate when he's in Mafia "enforcer" mode. I've had him vomit on my comforter (he sleeps at the foot of my bed,) on the carpet in the main walkway in my bedroom, on the living room rug, and finally tried to grab him and get him to linoleum before he erupted.
Evidently, he's gotten the message.
I went into the guest bathroom the other day only to see a pile of undigested and partially digested Science Diet cat food in the stool, some on the back of the seat, and some on the white porcelain flat area behind the seat.
Nice shot, Jabby!
