Thanks for the advice about the burrowing. My bf and I made bunny a condo out of those office crates and she seems to love it. The massive burrowing has stopped now that her cage is bigger. I actually stuck the bottom of the other smaller cage inside the bigger one and she seems to like using that as her litter box. I filled it will hay so she has a big are to graze and poop and pee. And so far the litter training is going well. When we let her loose in the house, she tends to go back to her cage to poop and pee 90% of the time. I only found a few poops around the house so far. But at least those are easier to deal with them cat poop. And speaking of cats, my kittens are adjusting to the bunny well. One of my kittens (Toki) was able to cuddle next to me on couch last night with bunny a foot away from her (bunny was on my bf). And it seems like bunny is happy and adjusting well too. She did numerous binkys last night. It was cute. I never get bored watching her hop around my living room.
