[souffle]

How odd. I've never heard a vet recommend Jelly for a hamster. I suppose it must provide fluid and some sugar post op. To function properly a hammy bowel must have a lot of fibre in the forum of seeds and nuts and this must form the main diet however in the wild they will eat insects and grubs for extra protein and the chicken is a good source of this. Just a fingernail sized bit though maybe once a week. Also a tiny bit of fruit or veg a couple of times a week is OK. Too much can cause looseness.
Get your little boy up at a suitable time and let the girls enjoy their pet. Good luck with him. Hope to see some pics of him on the forum. What is he called?
