Set rules immediately and stick really close to them.
Avoid situations that promote inappropriate behavior.
Observe Fifi and provide what it needs to be cared for and attended to.
Supervise the new pet diligently through undivided individual attention
and training, and restrict the pet's access to a limited area of the house
until training is complete.
Encourage good behavior with limitless praise and attention. Make a commotion
like, "Good Fifi!". Make your pet feel good.
Correct bad behaviors by providing positive alternatives. (A toy for a
slipper, scratching post for the sofa.)
Never physically punish or force compliance to commands. This may lead
to fear biting or aggression.
Don't play rough or encourage aggression or play biting.
Expose Fifi to people, animals, and environments where you want them to
live.
See your veterinarian if serious or unresolved behavior problems exist.
