My family's solution for the feeding dilemma: both kinds. Dry and wet.
The cats get wet food every day around 5pm, and only a small portion, maybe 1.5-2 ounces. It's Friskies brand Special Diet, for urinary tract health. They're thrilled to have it, but it's not really much more than a small meal. If they're hungry any other time, they've got dry food available, which is Purina One brand, also the Urinary Tract Health stuff.
That's been the diet of the pairing (sort of) of cats I've got now. I say "sort of" because one died not too long ago around age 14. As best as the vet can figure, he must have had a stroke, and then he started having seizures. We tried him on medication to calm the seizures, but it made him so loopy that he was having trouble walking, so we had to lessen the dosage. One morning then he laid down in a sunbeam, and either had a seizure that stopped his heart or breathing, or else had another stroke. He never woke up from that.
The other cat of the pair, Beverly, Scotty's sister, is still quite alive. She follows us around like a small puppy, and has a rather diverse vocabulary, making all kinds of unique, specific sounds concerning what she wants to do. She's also got a "convenient" warning system if she is about to throw up - a very distinct yowl that serves as a 10-second warning to impending barf.
Previously, the longest lived cat here died at age 17. He ate store-brand Sardine-flavored wet cat food, and Meow Mix dry food. He was euthanized at that age due, to a large tumor growing on his back leg. Other than that, he was always in fine shape. He was declawed when he was young (front claws only), but he still got outside once in his later years and managed to climb a tree. Then he whined and complained for a few hours, but came down on his own.
