I don't use the shredded paper as litter so I honestly don't know, I use
Kiln Dried Pine I buy it from a local feed store here a big bale is like $4 and I usually buy 2 at a time. One bale between the cavies, degus, and Chinnies usually lasts me for about a month. So not bad at all..... As for toys go to the bird section of your
local pet store, they love to climb on things and most bird toys have the wood blocks for them to chew on as well. Back to the bedding, I had always hesitated on the pine, but with so much advice I had gotten in here, I stayed with the Kiln Dried but then found out about the feed store carrying them in much much bigger bales and for way way cheaper.
Good Luck
