I disagree about getting 2 cats. We've had 6 cats over the last 35 years and twice we got 2 at the same time and they never got along. First time it was a boy and a girl, both fixed. Second time two fixed females. And my wife's best friend is beside herself with 2 cars, one is the downstairs cat and the other the upstairs cat, both fixed females and about twice a year she ended up with at least one at the vet for treatment of fight injures. While sometimes cats will get along, I think those cats are in the minority.
Our last cat is the only one who ever got wet food, and that was because she was allergic to all poultry and could only eat fish.
But the reality with cats is, they are so unpredictable in their preferences, not sure anyone of us can give concrete advice.
The best way to get two is to get litter mates. My two girls (Mickey is no longer with us unfortunately

They are now much more independent since the more timid one has gotten a bit bolder. They get in little scuffles but never anything that causes cat fur to go flying and definitely nothing to cause a vet visit. Most of the time its just hitting each other with paws, a bit of wrestling, or a hiss or two.
