Free range guinea pigs could result in 600.00 in fines

[Catherine]

A couple in Brisbane has a herd of free roaming guinea pigs. Everything is fine as far as the piggies are concerned. The twenty guinea pigs have been living free for two years.
It seems that this is against local bylaws. The couple will be fined 600.00 if the piggies are not contained.

The idea of free roaming guinea pigs is pretty exciting. I would love to see it, but on second thought, maybe not. It seems harsh to fine someone for having guinea pigs on their lawn. However the guinea pigs are clearly capable of living in the area. What if some of the herd move on and establish themselves elsewhere. They can multiply quickly. Guinea pigs as an invasive species may not seem to be a threat, but herds of guinea pigs could easily strip local vegetation and kill off food sources needed by native species. They would have no natural predators and they could multiply and seriously upset the ecosystem of any area they invade.

Maybe a little fence would be enough. Guinea pigs don't dig or climb so it wouldn't have to be a big fence.
