Hi Hix, I don't suppose if you can explain how this 1m fence keeps the Kangaroos in? Is it the rocks on the floor keeping the Kangaroos away from it? I'm confused, thanks!
@ZSH The same mechanism by which many zoos keep their kangaroos and hoofstock in. Theoretically they could escape but as they see their enclosure as their safe territory there is no need or wish to escape.
