iorek has started getting mats between his toes on his front feet. it is not between every toe, just the same 2 toes on both feet. i don't know why he could be getting them there. it seems like a very strange place to get mats to me. i cut one out a few months ago and now he has one on each foot. what can i do to prevent them? his fur is not super long on his feet. i can't exactly brush between his toes or at least he wouldn't like me to!
