 Another type of enrichment we do is ice cups, which is a small amount of squash and forage mix sprinkled in frozen and this is just something for them to do. Basically they have to pick the forage out, they have to crush the ice, it's just something different, a different way of delivering a form of food. These are the ice cups look like, it's just squash with forage mix like I said. We give one ice cup per monkey and we just sort of stick it through the bars and I'll pay for it as a fit, there we go, back off, like that, good girl, Ollie mate, you all right? Good boy. Other enrichment we can do is stuff like these plastic bottles, drill some holes in, put forage mix, little bit of cereals and plain popcorn in and put hay in and this just helps and there's a little puzzle for them to figure out, get all the food out. We can do it with car boards, food boxes, it's all the same stuff, it's a different way of delivering it. Just empty it out, pick the best bits out, not too bothered by people go past the window, that's interesting. No, if you stop out past the window then you do.
