Why cats are more clever than babies

Cats use their heads to determine if they can fit through a particular space.
This is because on a cat, their head is the largest part of thier body - If their head can squeeze through somewhere, inevitably the rest of them can too.

Babies also use their heads - mostly because when they are crawling, this is the first part of their body to find a place that needs squeezing into.
Unfortunately, on my 14 month old, his shoulders are actually wider than his head - thus he tends to get stuck a lot and cry for help to be extricated from various nooks and crannies that he's gotten his big noggin stuck into.

While this is amusing for me to watch, for a few minutes - I eventually feel sorry enough for the little guy, and rescue him, only to have him turn around and promptly get stuck somewhere else.

Cats are also amusing to watch - especially with an empty Kleenex box. They can get their heads in easily enough, then finding it empty they try to back up - It's most hilarious to watch the box back up with them, as it is light and grips their head just enough to not hurt but be incredibly annoying. I've seen a cat continuously back up the length of a room at near lightspeed trying to extricate themselves out of a Kleenex box.

A Kleenex box does not fit on my 14 month old's head, so I've not tried a comparitive experiment, although if I had a giant Kleenex box - I bet the baby would be more clever than the cat in finding a way to get it off - Even if it were to yell loudly until mummy felt enough sympathy to remove it, it would still be a valid method of head extrication.

So maybe babies are more clever than cats after all.
My experiments are far from over. Results to be announced at a later date.
