So I no longer buy mice from Petsmart because their sizes are way too inconsistent. I've been buying from Petco for a while at 2.30 an adult mouse or something like that. Expensive but at least they are the same size. I've noticed they haven't restocked the freezer in about a month and half because the other day I had to dig to the back of the freezer to get a mice his size. That's concerning. I'm thinking it's time I purchased online. Allure is about six months old now and he's gone up a mouse size since I got him at three months. If I buy online I want to move him to rats of equal size and purchase enough to make up for the shipping cost and still save some money. So my question is how often does a regular, every five day, eater go up a food size? I don't know if I should just get the whole thing one size or get mostly his current size and a smaller quantity of the next rat size up or what.

I really need to get a gram scale tomorrow.
