Maddox eats a predominantly wet/raw diet so he doesn't get a whole lot of kibble. However, there are days when I am away from home for 12-14 hours at a time and, him being a kitten, I want him to have something to munch on throughout the day so I leave out a small amount (no more than 1/8 cup) for him to snack on throughout the day. This creates the problem, though, that it takes him forever to go through even a small bag of kibble. The last bag of TOTW I bought him he only got through about 2/3 of the bag before it went rancid and I had to throw it out. I just bought a 2.5lb bag of Blue Wilderness and don't want to end up throwing out a lot of it too.
Any tips for keeping it fresh? I currently leave the food in it's original bag, air rolled out after each use, and stored in an airtight plastic bin. I think I heard somewhere that you could freeze kibble to help it last longer but I don't remember if that is correct or not. Any tips?
