truth. i *loved* my rats (RIP harry and oscar). ya gotta get male rats though, they're way friendlier. and 90% of the time the females are pregnant, even when theyre like 3 weeks old. but yes, highly adorable, trainable, and portable pets.
I have a small pack of rats living in my walls and ceiling right now. They frequently wake me up at night. I do not share your warm feelings towards this species.
Rats should do this often because they really, REALLY love to coat themselves with their own urine. It's some kind of throwback to primitive behavior. They coat themselves in piss so when they walk and brush up against things they leave a scent trail.
I like rats. I've had a lot of pet rats, but they are nasty, dirty little beasts.
Hamsters are just as cute and much cleaner. They can even be taught to use a tiny little litter box.
Hamsters suck. They're cute and all, but they tend to do things like eat their roomates and babies and pretty much any other hamster-sized animal they are placed with.
Did you try bathing them in shallow water like this person did? I always got scratched up because I tried bathing them by putting them under the running faucet.
