I am having issues where,my RATS aren't breeding and some people are saying it may be they need more. Heat. They are in the same room as my snakes and dogs. I have a 40 gal aquarium with my make RATS in and my females I have in 10 gallons on a per tank. When they were breeding I would keep the two in the tank until they were ready to drop them separated them to 1 mom with babies per 10 gal aquarium.I have been swapping a make out with my females every couple days and I haven't seen them mating and the moms don't seem to be getting pregnant. What would you suggest because I have 27ball pythons varying in many sizes and need Pups to med RATS to feed, and that gets quite expensive. Do you have any suggestions. They would be greatly appreciated. Thank you.
