Oxbow is a good food If you could avoid the same breeder I would try, but I understand that it’s important for rats to have a buddy. There’s just higher health risk if they are bred carelessly for snake food, especially if you are unsure of the health of your little one now. Maybe you’d consider adopting a rat of the same age? I guess if you absolutely had to pick another from the same person avoid those markings. Just things to consider.
