Not much though, in fact not at all truth be told.
To explain, I'm having a clear out, throwing stuff away, shredding papers etc. What Bob does is steal stuff and rip it up. Or if he is outside comes in and out with 'presents' for me, bits of stick, wood, leaves whatever he can find.
Here are some pictures and a video to give you some idea of what I mean. (click to see pictures bigger)
A leaf
bit of stem
stolen envelope
paper shreddings
Oh, well.
