Does anyone here use or have experience with Science Selective rat food? From the ingredients, it looks okay, not as good as Harlan 2014 or Oxbow, so if I use it I'd probably supplement it with some other stuff- but right now it's on a huge sale ($10 for over 4 pounds, it used to be $20) so I would like to stock up if it's ok
