Thanks Im enjoying this forum!
I have taken your advice and swapped to a mix (Harry Hamster) and still put a couple of the hearts in to ease her into it gently.
She does seem to be loving the foraging and my daughter nearly died laughing watching her trying to stuff a huge peanut outer into her already full pouches - she gave up, stabbed it with her two front teeth and then tried to get it down her tunnel (hilarious).
I have noticed too, which may or may not be a coincidence, that since changing to the hamster mix she is less smelly. Our robo was not smelly at all and we all commented how we could smell the syrian more when she arrived, but since swapping she seems not to smell at all (maybe its like adults having garlic breath/asparagas wee)
