I get my carefresh direct from carefresh--it's about US$19 a bag, including shipping, which is the best price I've found anywhere. The dropping of the other shoe, however, is that one order is five bags. But with one pig and 8 rats (in two cages) my gf and I go thru the stuff pretty quickly.
I feed Harley Gertie Guinea
Pig food (can't remember who makes it--same company that makes Reggie Rat and Harry Hamster). I love my Harley, but he is the most *@#% picky eater in the world! Only eats peeled carrots; I waste most of any other packaged food.
Consequently, he gets a lot of romaine and lettuce mixes, baby spinach, and blueberries--I sprinkle vitamin powder onto the veggies for extra Vit C (less waste when sprinkled, and he gets a measured amount of the vitamins). He seems quite healthy; the vet agrees at his yearly checkups.
