I brush Tosca a few times a week but it just seems it's never enough for behind her ears. It's like those ear wads creep up on her really fast and almost spring up or something. It's almost like Hey where the heck did THAT come from? I untangle them the hard way before they get large, but she hates it even if they aren't that bad. I know that if I let one go, it will turn into a bigger knot in no time flat. Is there any safe product out there that eases ear tangles that I can use on her when she starts to get knotted?
