When this reserve but then buys for guinea pigs, one must always be clear how much space so need a piglet. Pro females you need (in a cage!) And at least 0.5m² per male at least 1m² space. Since the outlet should be even bigger than the cage but, as the name suggests, you should already einrechnen more. So you should either buy the same or more grating, like me, who ends up leaning walls. If you still something leaning against the outside of the open ends, it can no longer be postponed. And with a grid can be achieved in this way already 2-2,5m² about.
For the gardener it is, however, of course, only under strict observation. Almost every attacker in nature would feel downright invited by such a grid. Jump martens and cats (or Hounds) and climb over it and crows attack from above. (Due to the low amount no more power would help since. The attacker would sit on, the power thus drops almost to the floor and the pigs get from at least bad injuries.)
As it is, however, ideal for my purposes, and I already have something else for the garden, I like to give 5 points. The construction went very einfachund just so apart the grid is with me even at any point. Anyway, there have not yet managed to overturn him the pig.
