First I must apologize for my bad english, but I hope you'll understand what
I mean.

You see, my parents have a little problem.

They have a cat that is nearly 8 years. She is very nice to both my parents
and to me when I'm home, and she likes to cuddle and likes to be where we
are. 1 1/2 years ago she got kittens. We decided to keep one of them and
gave away the others. Then after a while she got more kittens before we
decided to take her to the vet to make sure she didn't get more. We kept one
of those too. For a while, all three cats could sleep next to each other in
the same chair, and played and cuddled with each other. Suddenly, after
about 6-7 months, the mother started to reject the kittens, and scared them
away if they got to close to her. Now, if she so much as sees one of them,
she makes a sound like "get away from me or I'll hurt you".  The two
kittens, on the other hand, are the best of friends and can't get enough of
each other.

Is it normal for a cat mother to reject her kittens after a while, or is it
because she had had my parents and myself for herself for nearly 7 years,
and suddenly she got competition? We are aware of the problem, and tries to
take extra good care of her, but it doesn't seem to help. We really wants
our cats to be able to live with each other, because we love them all to
much to give any of them away. Help... is there anything we can do?
