Dr. K thought it would be a good idea to keep track of the Fat Rat weights. I've got small, spring-loaded food scale--and after the first weight session, I have some concerns about how accurate it is. . .though I think we're looking for trends (is the rat losing or gaining weight?) rather than needing an absolute correct weight. Weights in the extended entry.
Metro: 800 g
Kono: 820 g
Calle: 1200 g
Olie: 880 g
