We've had a lot of hamsters since 2006 and the the majority of the females were 200+g the males are usually smaller, but some of ours have been 200-260g our smallest male (shearer, who was a short haired black and white banded, he had dark red eyes) he was 128-144g and he was our longest living hamster, living to 2 years 10 months and 2 weeks
Long haired males are usually smaller that short haired males
They seem to reach max weight 9-12 months
We have had many females (all pet shop) reached over 250g one nudging 300g (lily) she was a long stocky hamster, she wasn't fat
We thought she was big, until now
We recently got a pure bred hamster from a local breeder, lovely little thing.......then she started growing!
Bernadette is not even 5 months old yet and at her last weigh in she was 321g yes that's right, I don't have a teddy bear hamster, have a bear lol
She's lovely and friendly outside of her cage, she's very protective of her home if you put your hand in you will be lucky to get it back
She lets you know when she wants out, it's her rules we live by, she rules the roost.
321g this was a week or two ago. She is due weigh in tonight and she looks like she has grown again, my hand is getting too small to pick her up.
She is too big for the 12 inch trixie wheel so we have a rat/chinchilla wheel that is wide for her.
