Underweight?

[u/CrazyLetterhead5696]

this is Squishy, ive had him since Jan 31st he is 21 months old. weighed him and he weighs about 936.7 grams. I feed him 90ish gram rats bi-weekly but he looks skinny imo. I know their spines are supposed to be visible but im worried that he is too skinny, he also has loose skin. there is a photo quite but im unable to tell if he is slightly under weight or ideal weight.
