I'm wondering if you guys could give me any input on how old my baby might be.

I got him (I say him, but I really don't know if he's a boy or a girl) in May as a gift. At his widest girth he's maybe the size of a quarter, a little smaller. When I weighed him last week he weighed 91 grams. He's eating like a champ (2 hoppers weighed as close to 15% of his weight as I can get) on a 6-7 day schedule, and had his very first poo in his cage today!

I don't know if there are only specific times that breeding occurs, but I'm curious to know his age approximately so I know what month to make his birthday. For some reason, it bothers me to not have a month in which to celebrate pet birthdays. I know all my animal birth months...well minus the cat that we rescued as an adult from the jaws to two angry dogs...but you get the idea.

Thanks!
