Okay guys, thanks so much!
Yeah, I give Pip about half a cardboard paper towel tube every once in awhile and she can usually eat it down to about half of the half. She chews on boxes I put in the xpen for them to lay in, but that cardboard is usually left in pieces inside the box, so they use it kind of like bedding. They always chew the same part of the box too, right in the middle of the entrance or exit. I think that Pip needs to be able to get her big belly through the opening a little easier. ^_^
Fiver just ate almost all of a half paper towel roll tube in the last few days. But he also loves his hay too much to just make a meal out of the tube.
As far as the tubes are concerned, I never see any pieces of those left over. They’re definitely swallowing them. Except for Mimzy, who doesn’t seem to care for it one way or other. I don’t know if he just doesn’t care for cardboard anymore or if he is still having tooth probs.
