Because such was not expressed in the OP, which is the specific scenario I'm debating. What's more, if avoiding possible species jumping diseases is the concern, than no one should be allowed to have animals anyway.
*Edit*
And EVEN more, we're moving into an era where people are decriminalizing transmitting STDs like HIV/AIDS by not warning the other party because those diseases aren't considered to be certain death. While I'm firmly against that policy, it does seem that anyone who'd approve of it would be hard pressed to make the case about protecting an animal is such a case.
