Those things are so horrible. Duke picks up a couple every now and then, I don't know where from, but I have a cat who I swear has 3x the amount of hair as duke, and wherever he roams to, he picks up tons of them! I know what it takes to sit there and pick them all out, poor baby. It's bad when they are on their face too.
Good thing you are moving soon!
Hopefully your new place wont have them!
