Thank you MJGB. As soon as I find something she likes the next day she does not wish to know. I tried playing with paper balls yesterday, but that what ignored, so I wrapped her nuts in paper and put them on the top of her cage, too easy. Within a minute she had pulled each one through, nut found and eaten. So now we are looking for something similar but a bit more complicated. Just informed my OH about her new cage and the cost, after a gasp he quickly resigned to the fact, he usually likes to protest for hours, days, weeks..... We are getting him well trained.
