Aaah! I've had rats that have gone through *ridiculous* squeaking phases, for no apparent reason. I think some rats realize that squeaking makes other rats and people leave them alone a little more, so they keep doing it until everyone starts ignoring the squeaking, and then they stop.
One of my rats likes to crawl in my sleeve and squeak bloody murder, as if someone's attacking her. Repeatedly. You'd think she'd learn that a) she shouldn't keep doing it, if she doesn't like it; and b) squeaking doesn't do anything. Silly animal.
