No, none of them do I've gone in to all of the ones remotely close to me (there's not many) and called a few others. I can't imagine why they wouldn't. The pet store close to me the next state over is who I've been buying mice from, since they're larger than Petco's (and cheaper!) Though, maybe Petco's rats would be really small too... I should go and look. One of the stores I went into, I asked what sizes the frozen rats came in and he looked at me like I'm stupid for a few seconds before saying, "Small, medium and large." So I thougth maybe it just wan't common to have smaller available. (well, it isn't around here at least). In fact, the only two actual reptile stores near me don't have anything smaller even live (even if they did, I'll do what I can to avoid switching to live when he eats frozen so well).

I will maybe just bump the mice to every 4 days instead of 5. He grows like a weed so hopefully it won't be too long before he can take a rat. I don't want to hurt him by feeding too large, so I will take the cost blow and just do the mice more frequently.

Thanks for the input everyone! Much appreciated!
