I once adopted a little rabbit that had been abandoned on a golf course. He quickly started using the litter box and eating the cat's food - which gave him the runs, and I wanted to stop quickly. We named him Claude Pepper, after former US Senator Claude Pepper, because his hind claws would rip you open if you pissed him off, and his poop looked like peppercorns all over the living room floor (until he started eating the cat's food, at which point he got a cage outdoors where he could munch grass all day and be continent). I lashed the 2'x2' cube covered with chicken wire to stakes and moved it every day, so he'd have fresh grass to eat.

Sadly, the cats did not protect him from a hybrid wolf that escaped captivity, snipped the ropes holding down the bottomless cage in the back yard, and moved Claude on to the eternal abode of all good cats and their rabbit buddies. It was fun watching the cats and rabbit play while he was with us.

Thanks!
