This depends on what type of cat you have. If you have a mouser or a barnyard cat they are obviously good at mousing. If you have a pampered, stuck-up cat that eats real meat and you prepare a meal for it like you do your family, then they are good at spending your money. If you have a fat cat then they are good at laying around and covering your carpet with their hair and smell. If you have a loving, well brushed, well trained house cat then this cat should be very friendly and a good lap-sitter. All cats should love their masters--people--, or maybe all people should love their masters -- cats -- , I'm not sure which it is.
