Ok so I have been trying to breed rats for about 4 weeks now with no luck...(the last time i had a litter it was so fast and by accident so i thought it would be fast also)... so I know how to tell if ball pythons are gravid but how do you tell if a rat is... i have pic below to see if you guys can tell me if they are pregnant?


Also when do you think they will give birth??

any help appreciated.

Rat #1





Rat #2




Rat #3
