Answer 3

I think that's not completely uncommon. I think I've heard of it before. It's called lordosis or something. I don't think it's anything to be alarmed about.

Answer 4

gender confusion my female dog thinks she's a male try's to pee like a male and humps female dogs, i thinks it's just something wrong with the brain physiology.

Answer 5

They do that because of dominance, just like dogs or other animals do.  I wouldn't be worried unless it aggitates one of your other rats.

Answer 6

she showing dominace just like if you watch meerkat manor they do that or like dogs to

Answer 7

Some humping can be dominance related, but I've noticed my girls like to do this when one is in heat.  If the one being humped kind of arches her butt up and holds her tail to the side, or vibrates her ears quickly, she is probably in heat.  Why the other girls want to hump her.. I don't know.  It's both disturbing and kind of funny, but nothing to worry about.
