This AM when I got up there was Juno's hair all over the hallway rug where she was rolling during the night. I should mention that I need to fight with her to groom her. My other cat loves to be brushed. Anyway Juno is medium furred. I was going to vacuum the hall before I went to work but when I was getting ready for work I saw Juno try to swat a patch of the hair that was on the rug and then before I could do anything, she ate it. No wonder she's always trying to bring up hair balls. Somehow I need to get her to take to grooming, but why would she eat hair?
