The bones in the things they catch aren't usually cooked. I thought that was the big danger, since cooked bones splinter more easily and could cause internal injury.
Well, it’s better to learn about it this way, the easy way, and not the hard way.
I used to work in a holistic/froofy pet store. There are a lot of great options for cats. Frozen chicken and turkey necks (raw), smoked bones (the only way to safely cook bones for your pet to eat), cooked tendons (my cat is a freak for the turkey tendons, though she gets so hyped about them that I’ve had to pull whole tendons out of her throat and she now has to chew them while I hold onto one end…)
It’s just not worth the risk from human food bone scraps.
