Free range guinea pigs could result in 600.00 in fines

It takes so little to contain a guinea pig. A six inch fence would do. However it would be safer to have a taller fence. I think a foot is a bit short, but three feet is more than you need. I am sure there is a bylaw that tells you how high to build a fence. (there is always a bylaw)
It would be a simple thing to build a fence. The guinea pigs can free roam within the fence area. They might not even realize they are fenced. 

It is best not to risk guinea pigs running loose and multiplying.
