No idea about your cars, but my cats? Because they can eat them when I don’t feel them fast enough in the morning and then I have to the vet because they can’t yak them up or pass them.
I love the little gremlins, but they are both bonded rescue cats that have pica or something.
Eventually, when the cats get older and no longer wash properly, we too will get a Hell Bag. I’m almost looking forward to it…
