IAMS Advanced Nutrition Adult Cat with Chicken

I use the 10-pack to feed stray and semi-wild cats that come to eat in my garden. The kibble pieces are huge, the cats can't chew them, so they either eat much less and lose a lot of weight, or they swallow them whole without chewing and then vomit. I'm forced to buy the kitten version. Cats have small mouths and teeth that aren't like rodents', so kibble this big just isn't suitable.
