It can vary depending on how developed the kitten is, but the best time to separate kittens from their mother is when the kittens are twelve weeks old. Ten weeks at the very earliest. At this age a kitten is be able to walk and run, its eyes are open and is able to eat solid cat food. Some kittens are not fully weaned, or know how to use the litter tray at eight weeks old.
However, the most important reason for keeping kittens together until twelve weeks is socialisation. Kittens learn very important socialisation and behaviour skills from eight weeks onwards. During this time kittens will learn how to play and interact with their littermates, mother and any other animals and humans in the house.
About 10-12 weeks old. This gives the kittens time to be fully weaned and socialised.
A kitten should stay with its mother for a minimum of eight weeks and preferably 12 weeks.
The gestation period is about six weeks.
If you want your kitten to live a long and healthy life, you should not let them out unsupervised.
6-8 weeks
The mother cat will bite, chew, and eat the sac. If she takes too long, break the sac away from the kitten's face. But otherwise, let her finish doing it. Her licking stimulates the kitten to breathe. IF mother is in distress, grab a rag, hold the kitten inside the rag using both hands and vigorously rub to remove the sac and stimulate the kitten to breathe--then take mom and ALL kittens to the vet.
You should separate them at 5 weeks, but they wean off the mother around week 4.
Yes, but not for too long. But the mother might be pretty protective so make sure she's contained.
until you run out of antibiotic
I have a male black kitten and I named it Leo but his full name is Leonardo. Give your kitten a name that you'll be comfortable with for a long time. The kitten won't worry about it. There are no rules (shoulds).
Until it is 6-8 weeks old, since that's when it would normally leave it's mother. Most kittens stop drinking milk a little before then.
usually a week or so during mourning it cries out loudly making human voices
This has actually has happened to me before. You will feel bad about it for a long while, sometimes you go into tears, but there should be no harmful affect. If you killed a kitten that was in a litter by accident, then the mother wont care as much as you think. She may look for the missing kitten once in a while, but she would just get over it eventually.
