When we used to use newspaper on the bottom of the cages, we'd also screw up a couple of pages for them to rip up. I remember our vet once told us of another client with a hyacinth who used to hang up entire phone books in the cage
LOL MJGB - Chico gets whole phone books too. I collect a stack of old ones each year from the Co-op. He's just been ripping up a new one - taking a well deserved rest right now. Like with everything else, including newspapers, phone books are getting smaller.
I have tried phone books but no one took any notice. A while ago I did read that newspaper was not good for them but it is mainly what I use for the cages, Dusky always goes down and wrecks it within 5 minutes. Do we still have phone books?
I often see sets of encyclopaedias being sold cheap at boot fairs but always afraid of the flock getting too clever but I will say they have damaged quite a few of my books and magazines over the years, I have lots of newspapers in storage as a local garage will keep them for me.
