I've had Allure a month now I think. I bought "small adult" mice for him since that's what Garrick had him on. I bought my second box and the mice are much skinnier and a bit smaller. I ended up feeing him two today because he was pacing the glass two days ago like he was hungry (I feed every five days and today was feeding day). They changed the way they package the mice so I don't know if that had anything to do with them now having smaller mice (like getting mice from a different company). Not going to waste mice so I'll let him finish these up then looks like I'm upping his size. Next time I'll pull a mouse at first to see it's the size it should be. Just irritating the sizes are that different. I found one in the packaging that was like half the size of the last box of mice were.
