I had the same concerns with the Cuddle-E-Cup. I thought it was absolutely ADORABLE, but thought about what Toby would do to it... *thinks of many articles of clothing found in bits around the apartment* I recently picked up some table placemats (for humans!) at Kohl's department store in their clearance section. If you can find their clearance section (they hide it so well! I almost felt that I needed some form of Dungeons & Dragon's map to find it), they have an area for placemats and kitchen towels, etc. They had some nice, thick mats that were perfect for bunnies. They were about 1 1/2 to 2 feet and square. I gave those to Toby and Berry-Boo along with a towel and they are in Bun-Heaven. (Those are a life-saver for Berry-Boo too, 'cause the cage we got from SRR to foster her is wire-bottomed, but with the mats, there's almost no wire left for her to step on!)
Long story short, my buns like to chew EVERYTHING, and carpet samples, thick(er) placemats and towels are their favorite nesting material. Heck, you can even go to Goodwill and get fleecy baby blankets (if your bun won't chew them). Fleece is Berry's favorite!
*Note: I don't play Dungeons and Dragons either (if anyone laughed at me), and no, I don't have a problem with the game, it's just not my thing.
*Second editorial note: my roommate plays D&D and said I had to put that on here (I don't know why :twocents:?)
