We have two cats, females.  The younger one, Chloe (6 years), is dominant
and tends to chase the other cat away from us and from certain parts of the
house.  We put Chloe away at night in the family room and have since we
first got her so that the other cat, Snickers (9 years) can have some peace
and some attention from us.

The last couple of weeks, we've had to keep Chloe in the guest room while
she recovers from an injury.  Snickers has turned into a completely
different cat during this time.  She's back to her old, sunny self, spends
all day with us (she was previously spending the day in bed upstairs), loves
to play, etc.

Do you have any suggestions for how we can keep Chloe from dominating
Snickers once we let her out again?  We thought of putting her in a crate
each time she jumps on Snickers or drives her from the room.  What have you
done that works?

Thanks.
