[souffle]

I think you'd need to watch your hammies carefully with this in case they broke through the strands and then ate the fibres or pouched them just in case they did cause a problem. I'd imagine that most hammies would not actually bother too much with this sort of toy but you never really know what they may get up to. Try letting her have it supervised and see what she does. If she starts to chew it to bits then I'd not use it.
