Hey there

I find that a toilet roll tube (cut down the middle) always goes down well with my pig, and it's not dangerous that he eats it.
As for guinea pig beds and accessory ideas, you can always check out my site to see pictures of my pig and his things. He always has a tunnel, which is really popular for playing in and sleeping, also a cuddler bed (the small dog bed versions), a blanket, constant hay,a cozy, a rabbit rattle toy, and a chew toy.

Have fun with your pigs!
