Hello, if your reading this, chances are your pretty frustrated and I can relate to that. I just want to share my experiences in hope they may be of help. My house rabbit Autumn was always a huge chewer and digger and My rugs have more holes than Swiss Cheese to prove it. Being a Rex, she also has reoccurring sore hocks, but as soon as I laid down a very soft fleece blanket over the original wool rug she stopped digging and chewing the floor, her sores are slowly healing too. Check your rabbit’s feet and if they have sore hocks I’d definitely try covering the floor with Fleece blankets or throws (as soft and short fibered as possible) as this both stopped the destruction and helps the healing process in Autumn’s case. Even if they don’t have sore hocks, I would still give it a try as it seems to deter destructive behaviour. A cardboard box or castle can be substituted to direct the chewing and digging to something more constructive.
