Just FYI, if they just stopped drinking mother's milk they're probably about 5 weeks old, and it's likely that female babies may be pregnant. They have to be separated at 3 weeks of age to prevent the males from becoming fertile with their siblings. They often still nurse for comfort for a couple of weeks after that, but they're born fully furred and walking and start eating solid food almost right after being born and can survive without the milk at all if their mom doesn't make it through delivery.
We are as gods to the beasts of the fields. We order the time o' their birth and the time o' their death. Between times, we ha' a duty. - Terry Pratchett.
"Men have forgotten this truth", said the fox, "But you must not forget it. You become responsible, forever, for what you have tamed. - Antoine de Saint-Exupéry
