Until the kittens are weaned.
You shouldn't give dairy to a cat at all. It takes a certain enzyme to digest milk sugars and most cats do not have that enzyme. Cats don't need milk after they are weaned from their Mother. Milk is for baby cows.......not baby cats. Give them water......fresh..........at all times.
While cats may drink milk, Persian cats like any others, it is not particularly good for them. Cats generally lose the enzyme that allows them to digest lactose when they are weaned.
Usually at 10 weeks of age just as long as they are weaned from their mother and have had time to learn how to socialise with other cats (their littermates and mother) and humans.
Until her kids are weaned.
about 8 weeks
No. Cats cannot easily process lactose once they are weaned, but liver disease is not one of the effects of drinking cow's milk.
Just like most cats. Mom takes care of them after they are born and when they are weaned teaches them how to hunt.
They will be quite protective of the kittens until hey are weaned, but will thereafter revert to their old personality.
a month
This usually depends on how old the kittens are and the individual mother cat. Usually a female cat will come back into season after her current kittens are weaned. However, some cats' cycles can start again when her kittens are still very young, and some will not come into heat again for many months after the kittens are weaned.
it takes 6 months
