I too was picking out the bones pieces but I'm sure I wasn't getting them all.
But within the past couple weeks all 4 of my cats have tiny amounts of blood in their poop. I took in stool samples last week and everyone is parasite free. My vet asked what I was feeding them.. and I can't help but wonder if there is any relation to the bone shards and mystery globs of god knows what.
In any case I will no longer be buying it.... I'm not comfortable feeding it anymore. I shouldn't have to pick through their food before offering it to my cats. It ticked me off even more when I found that link concerning the bones in their canned food from June/07. They obviously never attempted to fix the problem. Sending me coupons for free food isn't going to remove the bones from their food.
