I'm mostly looking for ideas of what species of snakes can eat full-sized retired breeder rats.

So far, I have always fed my BPs mice. With a relatively small feeder breeder operation, it made sense to stick with one species, and since I have both BPs and corns, mice were a better species for me to breed. However, that is gradually changing as I get more snakes, the snakes I have grow, and I'm looking forward to buying more and breeding my own soon. So I expect within the next year or so I may start breeding rats as well as mice.

One thing I'm wondering is what to do with the retired breeder rats, who will be too large for both corns and BPs. I know I could probably get rid of them on craigslist, but I've been interested in expanding the number of species I have anyway, so this sounds like a good excuse to get something bigger. I was thinking I might get something like an RTB or a blood python, but I'm not really sure how big a snake has to be to take a full-sized retired breeder rat.

Suggestions, please?
