PureSnacks Chicken Breast Freeze-Dried Cat Treats, 29g/1.02-oz bag

I get these for my feral/stray to add to his canned for a more natural experience and he usually eats them however I find lately they are more hard, grissley, large and hard to break apart. Since he is older and likely has pretty bad teeth I want them smaller and more easily digestable as I cannot take him to a Vet. My crippled fingers struggle to break them and they get tossed out so I'm wasting money. They aren't cheap! They cannot go in the garbage disposal. They don't break down in there too well and I have to dig them out so what are they doing in his gut? Granted he snags mice/chipmunks etc but I still have my concerns. I will get them regardless but that is my complaint. Perhaps they are overly "dried".
