Questions about breeding rats

[meowmeowkazoo]

Rat kittens will wean themselves typically after a week and a half or so. You'll see them start to try hard food and try figuring out the water, and that's a good time to put them into your grow-outs or euthanize.

1 1/2 weeks is way too young to wean rats. The EARLIEST they should be weaned is 3 weeks, but if you're keeping any of them as breeders I would leave them with the mom until they are 4 or 5 weeks old.
