Perhaps the British are too good to their pets, but more interesting is a recent theory amongst psychologists that pets are very good for us.

The basic meaning of 'pet' is an animal we keep for 13 ______ rather than economic reasons. A pet animal is kept as a companion, and we all need companions to keep us feeling happy. But pets 14 ______ us more than mere companionship, they 15 ______ us to love and be loved. Many owners feel their pets understand them, for animals are quick to sense anger and sorrow. Often a cat or dog can comfort us at times when human words don't help. We feel loved, too, by the way pets 16 ______ on us for a home, for food and drink. Dogs especially look up to their owners, which makes them feel 17 ______ and needed. A pet can be something 18 ______ to each member of the family, but for all of us pets provide pleasure and companionship.
