I have recently had two litters of rat pups. Two moms one dad. Now that its been a few weeks i have reintroduced dad with one of the moms but the problem is he is acting real scared of her. So i try the second one same result. Has this ever happened to any one else? By the way i seperated them again. My plan is to go ahead and try this for a few hours a day until they are all cool again.
