It made a rather large lump in him. This was a very small small rat. I hand picked two of them. But, the other one is 10 grams more then this so he will not be getting that for a while. I'm going to find another supplier for rats beause the one I go to now has been unreliable in sizes. They gave me rats claiming they were rat pups. But when I weighed them they were only 7 grams. When a rat pup according to RodentPro is about 20 grams. So, Ares got a very small meal this week sadly.
