My cat had five kittens 7 July 2002.
1. How soon should I start feeding kitten food?
2. How soon are they ready to be separated from their mom?
3. How soon can we have the mother cat fixed?
4. How should I be teaching the kittens how to use the litter box?
The answer to most of your ques is between 6-8 weks. After the kittens are weaned mom can be fixed and they will start using the litter box on there own at about 6-8 weeks. Just have it avail. vetcare
