This might be binned for this, but they poo SO much.

They also squeak alot, its hard to rest sometimes.

To be honest, they scratch. One scratched my eye when i was smaller.

Burrows. Just burrows. I cant tell you how much times I had to fill burrows.

They have too much babies! I think my old ones had about 17.

The fact that the dad eats the babies if you touch them, they're so cute though! ;-;

They hop alot,this leads to the fact they will hurt themselves.
