It’s completely impossible for a cat owner to control where their cat roams if they are allowed outside at all.

I dunno, a house on my street has some inward sloping wires along the top of their fences. It looks inexpensive and seems to do the job of letting the cat roam their backyard.

I don't really know where I stand, but if dog owners have to have a fence capable of keeping their dog in, I don't see this as being impossible for cat owners - it just needs to be a cat fence.
