First, some advice. When you get your next kitten, please give her a real name, because when she escapes from the house and climbs 60 feet up the tree in your backyard, you are going to feel like a real asshole standing at the bottom of the tree yelling, "Tiny Kitten."Also, should the above scenario befall you or someone you know, do everyone a favor and refrain from dispensing the two most useless pieces of advice:
1) "Put a can of cat food or tuna at the bottom of the tree." If the cat can't figure out how to get down, aren't you really torturing the poor thing by putting a tasty treat way out of her reach? I mean, maybe if a fat guy got stuck up your tree, you could get him to scramble down for a plate of nachos and a beer, but cats don't seem to think that way.
2) "Call the fire department" They don't really do that, unless the volunteer fireman on duty happens to be the brother of the kid who ice skated over your daughter's fingers resulting in her getting eight stitches and a deformed fingernail, and even when they do do that, they are not very good at it.
You should also refrain from making the following statement: "You never see a cat skeleton up a tree." Because, while that may be true, it is not particularly helpful when someone is trying to figure out how to get their apparently-really-stupid-and-frightened-cat out of a tree. But if you do think the cat is dead and turning rapidly skeletal in the tree, try to do a little more investigating before you and your child break down in hysterics, sobbing things like "Tiny Kitten was too young to die," because it is highly likely that the cat is playing possum.
So, you ask, what SHOULD do if your cat gets stuck up a tree? Borrow your neighbor's 40-foot ladder and call my brother Andrew.
