In my experience of dealing with many cats, wheat isn't good for them. Their digestive systems aren't designed to handle carbohydrates such as grains and vegetables. Yes in a small amount veggies are okay, but cats aren't omnivores. They don't even drink much water because they are supposed to get most of it from the meat they eat from another animal.
Also, you might be at risk for a cat to have loose/bloody stools or throwing up a lot. This is because each cat has a different tolerance to grains and the such. One of my cats Micah, has had many dietary problems because of pet store food that contains too much of icky processed blec and too much grain.
I would instead try just cat nip toys or cheap wet food such as Tiki Cat or Natural Balance. Be sure to ask the employees if it's okay to feed the cats certain foods in case of allergic reactions and other health issues a cat may have.
