oh god, i feel another mythbuster suggestion coming on.
can you polish a cat's hairball?
i would not expect an outhouse kami to know that. unless you've trained your cat to use the outhouse.
not a hairball anecdote, but thankfully poo related:
my late lady greyhound, millie, an ex racer, had adopted me a few days before the incident. after a session in my front garden, she suddenly screamed, a high pitched scream of agony and death. (there is a term for that used by greyhound owners -GSOD- greyhound scream of death). i ran to her, she was limping and holding her right paw in the air and not putting any weight on it. she limped indoors and lay down on the futon she used as her bed. i examined her paw. no blood. no grating bones. she'd been retired from racing due to an injury to her paw, tho i didn't know which one. did she sprain her bad paw again? dis she tear something? i decided to let her nap for an hour then see if she was any better, before i drove her to the emergency vet. an hour later, i got her awake, and she still wouldn't use her paw, whimpered and limped... OK, vet time. one more check before we leave to see if any swelling had developed to point to the problem area. feeling between her fingers a bit more than before, i discovered that she had, resting on top of the webbing between her toes, a small pea sized lump of hard-dried (but not polished) cat poo. i brushed it out and she was fine.
p.s. - turns out the GSOD is a common breed characteristic used to let you know about major injuries like that, or on bumping into something soft, or having a pea under your stack of mattresses, or the 'other' dog's bum touched hers on the couch (daddy, he TOUCHED me!). minor injuries like having your skin removed by barbed wire, breaking a leg, or your throat torn out by a bull dog do not rate even a whimper.
here's a hug big fella haha I'm sure he will love it and cut down many imaginary enemies in your honour
