Too big
I use the 10-pack to feed stray and semi-wild cats that come to eat in my garden. The kibbles are huge, the cats can't chew them, so they either eat much less and visibly lose 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 such large kibbles just aren't suitable.
