Once Harley pooped out an entire roll of dental floss.. grabbed the end and he just kept on walking and it just kept on coming.
Christmas day he pooped out a stick about and inch long 'sideways' that got stuck at the 'exit'. Also, some staples, paper clip, all my buttons off my pj's and his plastic Avid Microchip tag. His poop is always randomly orange since his preffered snacks/treats are carrots.
And he always has some grain in his doo doo because whatever my horses drop when they get fed he snoops around and picks up. lol
