There are many of us who have some dry food junkies and they would die before they ate wet. Dogs don't do that, but cats can. Some cannot afford to feed wet 100%. It would cost me $1500.00 a month "just" to feed wet. Millions of cats all over the world eat dry.
I'm not saying i am a big fan of it. I'm just saying you do what you can do. So, you might as well feed the best you can and the healthiest diet. Leave nice cool water out. I never leave dry out for the outdoor strays and ferals without a nice big bowl of water.
It's actually cheaper, and healthier for the cats to feed a less expensive grocery store brand of canned food like Friskies, Special Kitty, or Sophistacat than it is to feed an expensive dry food. They come in large, 13 oz cans, and when you calculate the cost per oz, it's not as expensive as you might think--certainly not $1500 a month, even with 20 cats. Estimating a little high at 7.5oz of food per cat a day, Walmart's Special Kitty in a 13 oz can (5.4 cents/oz) would cost you $14.85 per day for 20 cats, or $445.50 a month. By contrast, something like EVO usually runs about $26 for an 6.6 lb bag, which is about 25 cents an oz. The canned food is significantly less expensive. If you get a cheaper dry food like Purina, cats usually end up needing about twice the amount of food because of the indigestible content, so you're paying more for the dry food that way, too. Also, you also save money on kitty litter, because you'll find that the amount of waste will lessen quite a bit.
The big problem with dry food and drinking is that no matter how much a cat drinks, it's never compensating for the loss of moisture in their diets, which causes chronic dehydration, which in turn can cause problems like renal disease. I went through this with my Gabby because she was fed a dry diet for most of her life, and I just had had no idea it was bad for her. She drank like a fish, so I never suspected she was dehydrated. However, cats don't have thirst drives like people do. If you see them drinking frequently because they feel thirsty, it means they are already at the point of dehydration. Pet fountains are a little different because the running water encourages cats to drink even when they aren't thirsty.
As for the dry addicts, have you tried any of the tips and tricks Dr. Pierson mentions on her nutrition page?

I understand that ferals are also involved, so I'm not trying to say that anyone is a bad person for feeding dry. Just wanted to provide some more information for potential roadblocks to fully transitioning. Sometimes people don't realize how feasible it actually is for large groups of cats until you do some number crunching. A good friend of mine, after hearing the dry food lecture from me a few times, told me that he understood the benefits of the wet diet, but he just didn't see how he could afford the canned food with 8 cats. Once I broke it down for him, and he finally switched, he discovered he was saving significant money from when he was feeding dry before. Not to mention the savings in potential vet bills.
