Timothy hay and rose petal from P@H

[Ria P]

I never heard of people giving hamsters petals of flowers to make the cage smell nice.
I scatter herbs and flower petals as an enrichment for the hamster to forage for and nibble on. Different hamsters like different things, some like to nibble on roses and others prefer parsley.
I think the hay and rose petals are edible but your hamster doesn't seem to like them wheras another might.
