1. cats are not low maintenance unless you simply neglect them
2. cats come house broken, if not, good luck.
3. decide if you want indoor or outdoor ... if indoor, then be prepared to have play time with your cats everyday for the next 10 -15 years or they will find something to play with themselves.
4. most cats you bring home will be covered with fleas ... you need to adopt a cat that is old enough for flea protection (use the stuff from the vet). if you have the brilliant idea of giving the kitten a bath, you will need to dry it and keep it warm -- cats are not good being cold and wet.
5. you will need food, water, litter, litter box, place for the cat to sleep, toys and patience.
6. Vet -- empty your wallet ... repeat often.
7. If you are not ready to make a life long committment then don't get a cat or dog ... get some fish.
8. consider getting an adult cat ... lots out there without a home, and they are a little more self-reliant than kittens.
9. don't give a pet as a gift.
10. if you have a schedule too busy for a dog, why would a cat fare any better? most cats that wander the streets have a life-span of about 2 years ... some hit by cars, attacked by other animals (including humans) etc.
And kittens especially need lots of care and attention in the first weeks and months that you bring them home ... it sounds like you are way too busy to make that kind of committment so why subject another animal to neglect or risk of abandonment when it turns out to be too much for you to deal with?
