The first time I weighed him was with a kitchen scale but it only had oz which I converted into grams but I went and got a scale from the pet store which weighed in grams and he's 202 , pet store says this is a normal weight but others are saying it's underweight. Arrrrrrgh! Frustrating! I'm switching to every five days but need advice on how long to keep him there until switching back to seven, is there a age that I should go by?
