One morning I went into the other room to get Red and Magic back into their room before I went out. Red was acting very strangely, yep more so than normal! He wouldnt get down and he was lying all splayed out and resisted being lifted off, which was very odd. However, when I lifted him, all was revealed. He had found a bag of Whiskas I'd forgotten about and had obviously been supplementing his diet. Again, like the shredded net curtain incidents, I didnt actually witness him do it but I'd say the circumstantial case was pretty strong.
