Ew, I don't even feed my dogs Milk Bones!
If you want to get a kibble locally, get a small bag of high quality, grain-free cat food. Or you can order Pet Pro Happy Glider, or Suncoast Wholesome Balance to give on occasion. I would personally order the made-for-gliders kibble, rather than feed the cat food.. but a good cat food would work in a pinch.
