Is it something like catnip to cats??? Daisy has to unstuff all her toys and then tries to eat it if she gets away with it. I think it's a ploy by the toy makers to make us buy new ones....What do y'all think? I've unstuffed a few myself and given them back to her, but not as much fun for her, I guess. And the amount they can cram into a little bitty toy--just unbelieveable to me. I also tried to sew a couple up, but that just made her more obsessive about ripping it up!
