I agree that maybe it would be best for her to give her cat away...obviously she doesn't know enough about them herself. "Teach" a cat not to kill...yeah, sure, whatever! What I'd really like to know is if she had "mouse" toys for her cats to play with. If so, then she was fostering that instinct, not teaching it out of them.

And just because one of her cats was rescued and the other came from a pet store says absolutely nothing about their tempermants (another thing she needs to learn). Terra, my tabby, came from a pet store and is much more agressive than Misao who I literally pulled in off the street.

I definitely thinks she needs to take CATS 101.
