If you don't have enough air flow in the tub the humidity will build up. They get very hot in plastic tubs. We have a tub that we put them in to move them to the snake room for feeding. Right now it just has a bunch of holes melted in it on the sides and top and they sweat. We are getting ready to cut out the top and put wire mesh on it to help with the air flow.

Ok, well i've finally got a visibly pregnant mouse after a month or 2. Strange is that it's the 2nd female that I added about 2-3 weeks from having the original male and female I bought.

So, now that the mouse kinda looks like a golf ball, how much longer does it usually take? I just cleaned the cage so hopefully it'll be somewhat clean when she pops.

Also, the original female that's been in the cage like 3 weeks longer than the mouse that is pregnant. Is it possible that she's broken, doesn't breed, etc..? Should I ditch her?

The pregnant female has been gaining weight even before I could tell but this other one isn't at all.

Does the color of the mouse make a difference? The male and pregnant female are blended colors but the other female is plain white.
