I had just bought a digital scale, and it has this good sized plastic tray that sits on top(6.5inx9.5in). My ball is around 9 months old and overall a pretty good size, and it's near impossible to get him to be able to curl up enough or be still enough to stay in that tray so i can way him lol. How do you guys weigh yours, being that any of you have a scale similar to that? Thanks so much guys![]()
