It's bad to aggravate an animal.
Jeff's cat is growling and hissing at Jeff's friend Murray who has come to visit.
Murray wants the cat to stop hissing.
Murray gets down on the ground and puts a hand out for the cat to sniff.
Murray hisses back at the cat and pretends to try and swipe at him.
The cat slowly approaches to smell Murray and stops hissing as he does so.
The cat's hissing stops but only because he is now lunging at Murray's face.
