We’re on our second male Syrian hamster for dd, who is nearly 13. Eldest dd who is 22 also has one, they make lovely pets with the right care and it’s been a really positive experience for us. 😀
Female hamsters can give off an odour. Males don’t smell at all, and if you use good hygienic bedding available now, e.g., carefresh or similar, clean out regularly and spot clean their loo corner in between they never smell. Dd had a bit of help with cleaning at first but does this all herself now.
None of ours have been ‘bitey’. After a couple of days to settle, spend (supervised at first) time with them on a daily basis, learning to hold them and feed treats and with the right gentle handling, which an 11 year old is easily capable of, they can become extremely tame. We had gerbils with ds1 and 2, and Syrian hamsters are much easier to handle.
A proper large size cage is a must, natural housing within that and lots of natural chew toys etc mean they don’t gnaw the cage bars out of boredom, which would be noisy at night, and get a separate low noise wheel, not one attached to a cage. Make them a nicer environment and they’re a lot happier and they make a tame and very sweet pet.
We have seven cats by the way and it’s not been a problem at all.
