A lot of times, this can be the drinking valve of an automatic waterer or the metal tube of a water bottle. These rabbits can create a big mess in the rabbitry by pulling on these items. Some rabbits will grab on the front of their hutch with their teeth and pull like crazy. Some pullers are able to pull with such force they're able to make the hutch rattle. Pullers also love to yank on the part of the hanging feeder that sticks into their hutch.
Pullers have the strength to shake all of the feed pellets out of the feeder.
I named this type of rabbits barbers because they love to eat hair. Their poor victim looks like they had a bad visit to the barber shop. Rabbits that are Barbers get their in one of two ways. In the first way, Barbers reach through the weld wire and pull the fur out of the rabbit in the next hutch. You can stop this by putting a solid divider between the hutches.
