when to kittens start on kitte food, how do I do that and when do they use the litter box?

You can introduce your kitten to some canned food now, but you better have the litter box in waiting. As soon as they start on something other than moms milk they will be needed a litter box. Don’t worry about training them to use it just show it to them and they know what to do. That’s the great thing about kittens it hardwired in them to use the litter. You should have mom on kitten chow too so that she will have the extra nutrients to feed the kittens. They are usually weened at 6 weeks of age as that’s when they start their vaccinations. Up to this point they have gotten immunity from mom but now its time to be on their own. Once the kittens start eating food they will need less from mom and her milk will dry up within a few weeks. She will let them know when shes had enough with them.
