Rice digging box?
Has anyone tried using rice in a digging box for rabbits? I've seen some instructions on how to build a digging box for ferrets using plastic tubs and plain white rice, but I'm not sure if it would be safe for the rabbits in case they eat some. Any ideas or experiences on that?
The other material I saw recommended in one HRS article was corn cob bedding. It listed it as safe, but other articles say it can cause a fatal blockage if swallowed, so I'm not sure WHAT to think. (Also, thanks to recent grain-mite problems with the bedding, I'm having second thoughts about it anyway.)
What else would you try putting in a digging box? The typical paper, phonebooks and cardboard don't seem to be that appealing to our bunnies, although they do like to dig. They love digging in plain, pesticide-free potting soil when we give it to them, but the mess is just absurd, so I was hoping to come up with something that has a bigger grain size (for easier cleanup) that won't kill them if they eat it.
