Current cat loves to eat cellophane or any type of crinkly plastic. Packaging has to leave the house immediately as she will demolish the trash to get it. We can’t wrap a present and leave it for a day or even an hour.

My cat is obsessed with putting her toys in the water bowl. Dunking them, then bringing them to me leaving soggy puddles all over the place. It's clearly some kind of hunting thing since she plays with the toy for a while and then "it's time to put it in the water" - but I don't understand what her instinctive motive is doing.

It's annoying, but also fascinating and totally adorable.
