True that! I just started breeding mice and i'm keeping records and tags on cages of who bred with who so i don't inbreed! I work with mentally handicapped people, i would not create mice like that.

i am breeding mice of my own for a pet snake, i had bought what i thought was a prego female... and sadly it was nearly a month ago and she has not yet bred yet or whelped her babies.... i am worried although she don't really look at all much bigger then when i got her... can this be a problem?

With mice breeding you want to start with the healthiest, most attractive mice with the best dispositions. Try to get them from a respectable breeder. It's best to make sure that your originals are not related to each other, especially if you expect you will have some inbreeding. Learn to tell the males and females apart. If you want any control over their breeding, then you will need to keep the two sexes separated when you are not breeding them. They are colony animals though, so you should have them in groups rather than in solitary -- they will be happier that way. Males get along pretty well if they are put together as youngsters (and later only introduce new ones as sub-adults).

One person mentioned breeding mice while he was in elementary school and that he had problems with cannibalism. This shouldn't happen if you keep your mice well fed and uncrowded. Do not get into this if you don't have the energy to responsibly keep their cages clean and feed and water them regularly. They have high metabolisms and a lot in, means a lot out! lol

I breed mice and rats for my snake collection, and what you "need" depends on the size of your collection... if we're talking 30+ snakes, you'll want to get a 3-4 tiered rodent rack and at LEAST a 1.3 (one male, three females) in each bin. I can point you to some good sites, if you send me a DM - can't do that on the public forum without getting in trouble, LOL.

And to answer the original question, even though it's an ancient thread, there isn't anything wrong with interbreeding for one generation. Beyond that it's not recommended, since they can develop genetic issues as a result. Currently I have 1 breeding male (rat) with 3 females, and 2 of those girls are his daughters... creepy to us humans, but he doesn't seem to care one bit.

Wow another ancient thread.

They will also do this if there is too much inbreeding, they basically become crazy, some will be born with no tails, partial tails, deformed limbs, all sorts of physical and/or mental problems.
Sometimes males will fight to the death to mate with a female then ride her until she dies too.

Bottom line is unless you have a large need for mice it is much better to not breed but purchase the mice as you need them.
