We have a white cat, approx 18 months old, neutered female, which is
apparently deaf.  We're at least the third owner and she may have suffered
some mistreatment at the hands of a four year old before she moved in with
us. She is reasonably well behaved, affectionate and somewhat vocal because
she wants to roam the yard.

Our problem is she has discovered that there are cats living on the other
side of the street and just walks or runs over there.  Obviously she cannot
hear the traffic and has no fear.  I've even found her sitting in the street
on a couple of occasions.  Its not a busy street but it is used as a through
route by school buses and kids who pay no notice to the speed limit.

Any ideas how I can train her to stay in her own back yard?

We rescued our other cat, who is now a 10 year old,  from the parking lot of
an Olive Garden just a few yards from one of the busiest streets in Houston
when she was one year old.  As far as I know she has never even set foot off
the curb and sticks to the back yard all the time.  We assume she was
traumatized by the Olive Garden experience and to this day never meouws.

Any advive would be appreciated.

Thank you
