I'm not really sure if this should go in the behaviour section, or this section, but it sort of crosses over both.

Our new(ish) bunny, Winky, loves to tear things apart and generally destroy things. Last night she tore the stuffing out from the inside of her bed:

 What beds do people use for destructive bunnies? Can I let her keep using this bed, or should I remove it for safety reasons?

Is this destructive behaviour a sign of boredom? If so, what can I do/give her to alleviate this? Another night she went to work destroying one of those Oxbow hay mats, which our other rabbit, Dobby, had had for six months, and had only taken occasional nibbles at. She's a mini rex cross and the rescue did warn us that she will need lots of stimulation.

Silly Rabbit!

She's probably bored, and destruction is, well.... fun. Do NOT let her use this bed anymore because she could be eating the materials and that could cause digestive blockage. You'll just have to test out beds to find one she won't destroy. Chew toys and things like hay mats would be ideal for her if she's into destruction. I recommend you contact the rescue to see what types of toys she had and possibly even what beds they used.

Evelyn has never had a bed either. She flops down next to the closet doors and crashes. 

I agree with mocha200. Try giving your bunny a blanket and see what happens. Just don't let it get eaten!
