I absolutely hate mice, hate ASFs, but love the rats! They are so much fun. I've tried to breed mice, but they stunk so bad, and I had a lot of issues. Now that I have the ASFs cages so they can't escape I don't mind the ASFs, but just one trio of ASFs wastes more food than all of my rats combined! Rats are so easy, and they don't chew out of things even if they have plenty of room to do so. They are easy to breed, and they are much friendlier than mice and ASFs!!!! Granted you need a good beginning stock. Don't buy adults from the pet store, they are usually retired or bad breeders.
I say go for it!!
