I saw that people are selling rats and rabbits to Tom. So, I collected some dead rats and rabbits and tried to sell them to him and he said he only accepts fresh corpses and didn't buy mine. So, I wondered what can be fresh corpses? I went and killed one or two rabbits, carried them to Tom and sold them with meat and carrots inside them. This time he accepted and I thought fresh means that either meat or carrots should be inside the corpse. Then, after some time, I found that people were selling meat to Willie at 2 gp each. I thought, why should I sell a rabbit at 2 gp with 2 meat in it to Tom, while I can sell meat for 2 gp each to Willie to make 4 gp? So, I started selling meat to Willie. Only after a few days I realized that fresh means recently killed.
