I fed the natural balance duck/pea dry to my cat toby (possible food allergy).
He did ok on it (other than still having an allergic reaction)... It is pricey, but you can get coupons from the commpany and they have a buy (10 I think) bags get 1 free program... Also, it goes on sale at petco fairly regularly. You may also be able to get small samples from the company if you email them...I can't remember if they were one of the companies that sent me samples or not. All of my cats seemed to like the smell of the NB duck/pea and I had no problem getting toby to eat it.
As for wet, then only wet that I fed of those brands was the NB duck/pea and vennison/pea... Cats LOVED it! But, it is drier than most others I've used, so I had to add some water... It is also pretty pricey, unless you can get a discount on a case (the company also has coupons for, I think, $2 off the price of a case).
I have fed nutro natural choice, nutro max, authority, wellness, merrick, cal natural, and EVO cans... Of those, my cats seem to like the authority cans and the EVO cans the best...
Authority is cheap...at ~62 cents a can (6oz), loaf-style, and comes in many flavors...available at petsmart only and rarely goes on sale.
Nutro cans...are more expensive...~75 cents for the max and 85 cents for the natural choice... They DO go on sale and the company often has coupons or special offers... BUT I have never been able to get my cats to eat them...they don't seem to like the flavors.
Wellness is the most pricey of the cans I've fed...I actually had to order online. The cats only liked some of the flavors... I'd say the cans are at least twice as expensive as the two types I listed above. They do, though, offer some meat-only cans.
Merrick cans are more like a soupy mixture w/ chunks of this or that in them...My cats didn't care for them either. They are also pricey, although not as much as the wellness.
Cal. natural is available in big cans..12oz, so that's a bonus, as they are less expensive, then 2, 6oz cans. They're a little less than $1 each when I order a case on line. The bad news, is that my cats don't like them, or at least the chicken/rice flavor.
EVO makes regular cat/dog cans and they also have a 95% meat line, which is what I feed. I use the 95% chicken/turkey and beef...they also have vennison and duck. They come in the big cans also, and are about $1.20 a can when ordered by the case online.
I have also fed some of the lower quality cans...i.e. store brands, sheba, meow mix, etc. The big thing to watch out for is how much by-products, fish, and colorants are in them...The meow mix market select cups are not very bad quality, but they do all contain lots of fish...they are a "cuts in gravy" style, which my cats also didn't like.
For my money, the best "bang for your buck" is to go with authority cans or the larger cans of cal. natural or EVO IF you can find them at a good price locally.
