Thanks, Lisahe. I don't know if the bones in the foods we've tried are cooked or not, but they don't crumble like fish bones that have been pressure cooked. They're very hard, and have sharp edges, like sharp bits of gravel. Not something I'd want in my digestive tract, or my cat's. My search...
My cat also had bloody diarrhea that was determined to most likely be due to IBD caused by a food allergy, but when I mentioned to her vet that I'd found fairly large bone fragments in her Red Barn food, the vet allowed as how that too could cause bloody diarrhea. She has been doing really well...
