What do you guys think of their Instinct (grain free) canned food? I was looking at feeding either this or Wellness canned. I also found that the Nature's Variety cat food is exactly the same as the dog food that you can buy in the 13 ounce can. I went to the store to buy a couple cans of this and Wellness and found that the NV food rep had a bunch of $2 off coupons on the cans!
