Is it normal to eat things to dispose of them?
For example if I dig in my ear and get a big chunk of ear wax I just eat it off, ever since I observed this behavior from a cat. Also if I mess up my nail polish I just lick it off, if I have scraps of paper left over from crafts I eat those, and contact lenses that I'm done with. I don't enjoy or dislike the taste of any but eat simply to dispose of it. IIN
