Weaning. The University of California, Davis Goat Facility weans its kids completely by the age of 3 months. Much depends on the individual; some kids are ready to eat completely on their own before that, but others need longer.
At What Age Should Kittens Be Weaned? The weaning process normally begins when kittens are around four weeks old, and is usually completed when they reach eight to ten weeks. If you are in charge of weaning an orphaned kitten, please remember that weaning should not be attempted at too early of an age.
