My Tilly is happliy destructive as well. She loves to dig and dig and dig and chew. We put down some overlapping rugs in her area, making sure to let them overlap the baseboards a bit, so that she doesn’t just lift up the edges to get to the carpet, and gave her paper and cardboard to destroy. She also has a large blanket that is hers to do with as she pleases… she’ll dig at it, toss it, chew holes in it, and it saves the carpet since she feels she’s getting somewhere by being able to move it around… we just spread it back out when she’s done.
As far as the throwing litter goes, she does that too. I managed to get her to stop tossing it as far by increasing the size of her litter box; now she still tries to tunnel through the bottom, but when she starts digging most of it stays in the box.
The best thing for keeping her away from cords will be rearranging and creating barriers to them… as mostbunnies love to chew cords. I think they think it’s a strange type of hay. NIC grids are great for making barriers, just make sure that the wires are at least an inch or two away on the other side of the grid so that she can’t force her little face through and grab them.
Pet stores also sell products such as Bitter-Apple, No-Bite, and Yuk; that can be sprayed on things every couple days to deter her by making her think it tastes bad. I found Bitter-Apple works for my Pete, but Tilly thinks it’s candy coating. No-Bite seems effective though. My vet described it as tasting like pepper-spray.
As far as her spay goes; budgets understandably get tight. I would suggest keeping a jar for spare change.. That way you’ll have a slowly growing bunny-fund, and when you can squeeze a bit out of your budget you’ll have that fund to help cushion the costs. I have 2 jars, one by my washer/dryer for things left in pockets; and the other by my receipt book for change from shopping.
Sending good vibes to you and your buns.. and with your daughter as well!
