I use Wellness canned foods and have always been happy with them. I have 7 cats that love Wellness. I'm not concerned with the garlic content (partly because canned food is only a small portion of my cats diets and I rotate dry brands so they are never consuming much garlic anyway) although I do...
If you suspect an allergy to corn I would also avoid foods containing corn gluten meal as it is the protein/gluten in foods that most often causes the reaction.
I think the NB venison formula would be a good one to try. I've been very happy with the NB ultra formula.
I hate to bring it up because I can't remember the details but there is a specific reason (possibly toxins getting into the food or something once the can is opened?) that I stopped leaving leftovers in the cans. I put the leftovers in a plastic zip lock baggie now.

I avoid ingredients such as meat-byproducts, unspecific meat meals, beef tallow, unspecific fats (such as "animal fat"), corn gluten meal, soybean meal, artificial colors, flavors and chemical preservatives.
The Dr.Elsey's Precious Cat litter is 99.9% (or something like that) dust free. Its a clumping litter and comes in several formulas including unscented. I've been very happy with it so far.
I mostly use Innova, Wellness and Eagle Pack and I rotate amoung those. A couple of mine are picky about texture and these are 3 brand that all 7 of them go nuts for.
This is probably why there was such a price difference. Emergency vet visits are usually very expensive compared to regular vet visits because they are emergencies. My vet charges extra for emergenies if she is in the office at the time of the emergency but its still not as expensive as the ER...
Lots of things can cause kidney problems...protein is not one of them. I have done research as well. Old research theorized that high protein caused kidney damage, current research dismisses that theory.
Causes of kidney problems..this site lists several -...
Actually its not. Although it was previously thought to be, current research does not support this theory. High protein does NOT cause kidney problems in cats or dogs.
