My rat colony is getting a good size and I find I am going through (and wasting) a lot of food. The junk in the local petco ois both expensive and I assume could be better. I don't think the rats eat the grains and seeds. I got some kaytee blocks for now, but I am looking to take things to the next step. A staple diet of rodent blocks that I dont need to go out and get once a week at nearly 13 bucks for 5 pounds or under. I rather get a 25-50 pound bag for 50 bucks a month or something.

Does anyone have any recomendations where to get quality rodent chow? A URL would be nice

Thanks!
And sorry for not searching, my computer is not working well and I am borrowing my sisters, but at least I can pop in on my cell phone
