Go to the vet at least once a year.
Get vaccinated at least once a year.
food portions are depending on cat's weight buy toys/balls/cat lasers ,its good to exercise
organic cat grass
cat water-fountain
Lots of soft places to sleep, some high & some low
scratching post
balanced diet (good dry food (I use hills) and cans of wet food)
It's better to split the food like 3/4 of a cup in the morning and 3/4 of a cup in the evening with treats
Have multiple water bowl options they can choose from and keep them clean
Clean the litter box every day-- twice.
Hairball preventative made up of petroleum jelly.
It's best to use the lunch paper bags (to clean their waste)

Get some dewormer or other medical supplies like a flea treatment so you have it on hand if in need, if you can afford it.
Cat tooth-paste (they love malt flavor).

Start with a teaser toy for the cat.
Use Purina Pro Plan Urinary for adult cats. It’s at Petsmart, but little pricey. Other options available. Just give them 1/3 of dry (AM/PM) and split one can amongst the three. Cats eating habits differ.
Micro-chip it ASAP!
Find a good vet, preferably one that specializes in cats. Follow their advice. Find a list of plants that are toxic to cats -- never, ever have lilies in your house or yard. Consider that strictly indoor cats live up to 10 years longer than cats that go outside.

Pet insurance is very good advice. Maybe ask your existing car/renter/whatever insurer if they offer it, sometimes they'll give you a discount to bundle things.
Avoid wheat, gluten, & or corn as filler as much as you can.
The above is everything that people have suggested to me.
If anyone has any brands to suggest or maybe extra things that aren't on this list, let me know.
Also, advice on raising a cat.
Well-known as well as obscure advice.
If you're living alone, you may actually want to see if that cat can get a cat-friend at some point. Finding cats that get along with eachother is not easy, but they really do benefit from having another feline present.
Yeah, I'll start with one... for now.
Having two pets is a lot, but it is a good idea to try and get your cat as used to as many different people and animals as you can while they're young. Cats raised in complete isolation tend to be the scaredy-cats that hide under the bed when your mailman comes.
Okay, I didn't now that. I'll keep that in mind.
