Why is my mouse extremely thirsty?

Question

My mouse, Momo, he's been at the water bottle for 1O minutes about now, and he bites my other baby mouse, Coco. He's seriously been AT IT, and he won't stop drinking unless he's like... taking a break.

Does anyone know what's wrong with him?

Answer 1

Could have diabetes?  I would call a pet store.

Is Coco a girl mouse?  Maybe he's in heat.

Answer 2

mice move around ALOT and this is why they are thirsty all of the time  

Answer 3

there is nothing wrong with him its just like u when you really need a drink but mice get water slower so they need more time and i should know i have 1 boy and 3 preg girls
