They've had those around for a while, although not as stylish. I remember as a kid having to stick our un-spayed family dog in a pair of doggy depends.
I think Paulo has the right idea. Eventually the predators will get larger and there won't be as many. So instead of lots of annoying toads, there will just be a handful of wildly dangerous gorillas (yes, that is from the Simpsons) which would be easier to round up.
(Someone was doing that in Baltimore around the Maryland Institute College of Art campus about a year or two ago. It's a Thing.)
