Please help save two cats from needless harm.

My neighbor has two lazy housecats. There is a mouse in her house and she is
setting traps. The kind of mousetrap you bait with cheese or peanut butter
and when the mouse goes for the bait a piece of metal snaps down and breaks
the mouse's spine.

She insists that such a trap if sprung by a cat's paw would do no harm to
the cat's paw.

I believe she is wrong. Although I would never use such a trap in the first
place, even if I would consider using one I certainly would not leave it
where a cat might accidentally get a paw caught in it.

What I need is testimonials -- not opinions, but actual stories of injuries
to cats who've encountered such mousetraps and been hurt by them. I will
show those to my neighbor and hope she at least decides to put the
mousetraps out of reach of her kitties.

Time is of the essence!

Thank you.
