Here’s what *not* to do.
Don’t accidentally open a packet of kitten food for Kiska and think “Rats. I’ll just leave it on the side with a closed tin of food holding the end shut until tomorrow. There’s no way the kitten will smell it, jump up, find it, move the tin, take it to another room, savage it to shreds, and leave the ragged and perforated packet completely clean of kitten food.”
Don’t do that.
