Ichose "every cat should own a man" for an informal essay i have to write.
here is what i have so far. i need about 100-150 more words. any ideas what else to add?

"every cat should always have a properly trained human of his own around. there is nothing like a well-behaved person around the house to bring him his supper or to take on a nice walk at night. if it has been properly trained, a human can be a cat's tolerated companion.

the secret of a success in handling a human is patience. some humans do not listen well, but a tolerant cat who makes allowances and tries to put himself in the man's place will be rewarded with a loyal human.
the secret to a cat’s success is to pick out the right human. a cat should choose wiely when making his choice, since it would be mighty hard to rehome the human and have to find and train a new one.
although, not every cat who tries to train a human is successful. the answer lies in understanding. a cat must be patient, and not get too upset should his human learn bad habits. after all, "it's hard to teach an old human new tricks.""
