I picked up my cat earlier to cuddle her and to my great bemusement noticed a little clod of poo sticking to the fur of her behind. I grabbed a facecloth and pulled it off, which is when I realized it was in fact still connected to her insides by a strand of hair. I know that it's VERY bad to pull on anything hanging out out of your cat's behind...how dangerous is a strand of hair? Is it as bad as if they swallow a ribbon or other linear foreign body?
