This I know =p. However, the pinstripe and normal both continuously ate until I paired them o_O. The first week I paired butters to the normal, and the normal went off feed (pinstripe still ate). Then I paired butters with the pinstripe, and then the pinstripe didn't want to eat. I don't really want the calico to do this since she's been going GREAT this whole time. It's quite obvious that pairing the normal and pin is what shut them down.
