Thread: Leaving kittens home?

I'll be going on vacation for christmas, and need to leave my kittens alone for three days. They are old enough, and are often left home for long periods while I'm at work. I'm having a friend check in on them, but I'm still concerned that they might freak out. I'll probably leave out extra treats and a few new toys along with the extra food, water, and litter boxes, but I'm worried this isn't enough. Does anyone have anything they do to help ease the kitten's stress?

Leave the radio or TV on. And the heater if you live somewhere cold.
