Advertisement Got him back in April from PetSmart. not 100% sure how old he is, but I guess 4-6 months? He was about 5.5 inches when I got him mid april. unsure of what his weight was. month or so later he was about 6-6.5 inches and 10 grams. not he is around 7-7.5 inches and 23 grams. The pic on my hand is a few days after I bought him. On my Shoulder is within the last week.
