Sweep has Harry Hamster too. I am plannnng on trying him with some science selective, as a treat and then if he likes it possibly mixing it into his mix. He loves banana and strawberry. He had a bit of carrot once but we don't really buy them that often as we hardly use them. We tend to eat more frozen veg so might try a pea or two whenever we next have those. He loves monkey nuts. His mix does have some in but not many so now I have a bagful hiding in the cupborad! He also gets the occasional bit of walnut which is his absolut favorite! He also has other treats and things occasionally
