Either Miss Socks’ biological clock is ticking down (I guess she forgot the fact that she got spayed) or someone needs to go on a hunting trip. Every night (while you’re asleep), she will carry in, mewing all the way, stuffed animals and drop them in the bedroom doorway. She’ll sometimes do it throughout the day now too. You’ll come home and the floor looks like a graveyard. Very strange. Cute at first, now, it’s to be expected.
