While in the back yard tossing the frisbee to my Border Collies, I noticed a log of poop that had a reddish color to it. I wondered what that could have been from but didn't wonder too long because I ended up forgetting about it until a few days later while out back and finally decided to examine. By that time, the poop had dried and lo and behold, I found the culprit of the reddish color. My hair scrunchie. One of the little buggers ate my hair scrunchie and pooped it out!
I'll let you wonder whether I threw it away or washed it ;-P
