That is such a cute little kitty! I hope you enjoy your new feline companion.
My childhood cat is still around after 15 years and doing pretty well. We feed him twice a day and give a couple treats first thing in the morning and in the evening before bed. He's a bit of a picky eater and will only eat dry food. In his older age, we've been giving him food for sensitive stomachs.
Our cat is solely an indoor cat, but occasionally we take him outside to roll around on the concrete under intense supervision. He usually tries to eat grass but it always makes him sick so we stop him from doing that.
Unfortunately, my parents had his front paws declawed when he was a kitten (I was only 9 so I didn't have a say) and he now has arthritis in his front joints. I contribute that mostly to him being declawed. So I would highly recommend against that because I believe it's very unethical. Teach your kitty to scratch a clawing post and you shouldn't have any issues with furniture! (my brother did that with his two cats and they don't claw any furniture!)
Also, I find that my cat never plays with any expensive cat toys we get him. He plays with little stuffed mice and sometimes little jingle balls, but never played with any fancy toys. Paper, string, and other cheap things seem to be WAY more appealing to him anyways. Just always be mindful that cats like to eat the most random stuff (as other people have mentioned), so I would make sure you're supervising if your kitty is playing with them. There was one time when he was young and he ate a small piece of string that he chewed off,
Since our cat is older, we keep an eye on him fairly often to make sure he is doing alright health wise. Since he's been around for a long time, we can tell if there are any differences in his behavior and movement.
Anyways, not to ramble on about older cats since that's a ways away for your new friend, but I'm sure you and your new friend will have a great time together!
