I know this is a strange quesition, and one I should probably know, but I was curious. One of my new boys, Spike, has started to shred the newspaper that I put to line their indoor pen, and he drags it into this plastic igloo thing I have for them to play in. He has not long started doing this and it seems to be every morning I go in there that the pen is completely trashed and all this newspaper in shreds. He has been castrated, but only about a month or so ago. I mean, don't get me wrong, I honestly don't mind what he's doing, (although it is a pain to clean out in the mornings lol) But I just wondered if this was normal behaviour?
