The 2 oz., our "Snack Pak" is a starter size for those who are unsure whether or not their tortoise will eat a prepared food. And for use by a "Pet Sitter" when you are away.
The 9 oz. & 24 oz are our Tortoise Bites for juveniles & adults.
The Gallon is for those of you who have several tortoises. It is available the usual cut form or as a solid bulk from which you can scoup out what you need. Because there are no air voids you get up to 1/3rd more in the uncut gallon.
