 Cats are pretty self-soothing. Again, if your cat's really comfortable with you and you can keep it with you, I would. If it's going to claw you and get that nervous, I'd let it go find its space. Dogs are a little different. If your dog kennels, definitely have your kennel nearby. They'll probably opt to go in there. And if you're going to be away, turn on some loud music. And again, don't leave them with apologies. Say, hey, you're going to be fine.
