Hi! I adopted my hamster so I don't know her exact age, she is supposed to be estimated 9 months this July. I do know that she had babies in February. A month ago, she had a growth spurt and grew way longer - she is a Syrian.
She is quite long even for a Syrian, hence I feel that the vet at the rescue may have estimated her to be older than she actually is due to her length.
According to me there's no particular age when they stop growing, it goes different for every hammy. Still ,between 5-12 months they are fully grown in length.
