you should have to pass a test to be aloud to breed. or your pets.
My wife called me at noon today to ask if I was OK with her bringing 4 newborn kittens home that someone stuck in a muddy bucket and dropped off in the grocery store parking lot. Like cats or not. That should be treated like torturing a animal. So now we have 4 kittens that are about 3 inches long with there eyes shut in our house that we are hand feeding. Wife bathed them. And we are looking for a safe place to take them since we really don't have the time for them.
But all and all I think all people and there animals should be mandated sterile until they pass a test and show proof they can handle bringing a child in to the world. Weather its there child. Or there pets.
