I own a cat myself, and its great. Cats a re very low maintenance, so you shouldn't worry about much. But here are a list of things that I did for my cat:
1. Potty train the cat, so you do not worry about scooping stuff out of a box.
(I use the Citi Kitty to make my kitten use the toilet)2. Give the cat bathes a lot while he/she is still young, so that the cat will not hate bathes later on
3. Put catwalks in a lot of places. My cat loving loves catwalks
4. Try to use cups that have lids and such, being that the cat will like to play with your drink
5. Get a laser pointer. It is 100% true, that cats love lasers.
6. Show your cat a lot of affection. The move you care for him, the more he will like you.
7. Get a stick, put a 3 foot long piece of string at the end, cut a piece of cloth, and tie it to the end of the string. Kind of like a fishing rod. Then start swinging it in front of the cat.
8. Use the laser pointer, and "fishing rod" often! You do not want a fat cat, that can no longer enjoy the laser, catwalks, or fishing rod!
That's about all the advice I can give. Just let the cat be for a day or 2, so he can get used to your home.
