Well i will have to wait untill monday to switch the male into his own cage. Also how much does aspen bedding usually cost? How can you tell when your female rat is pregnant if you dont witness any breeding? I ask that because i will move them to a nusing tank so they cant mate when she is lacitating(sp?). also when i make that mix do i have to use all of those ingrediants as that is alot and will probably get expensive. I have a dog can i use her dog food in the mix? i forgot what brand it is. I will know when my mother gets home.
