This is so funny. I thought it was bad when Cat kept gifting Ianto live animals but I can't believe it started to steal all kinds of other things. I had a good chuckle picturing Ianto trying to return people's stuff in the middle of the night. Great story!
Author's Response: The things pet owners have to go through! Cat just wanted to show its appreciation for Ianto's efforts at being a good human, and if he doesn't like live gifts, maybe something that humans seem to like would do the trick. ;) Everything he returns will be in a plain brown envelope to avoid potential embarrassment. Thank you!
