Nope
We just can't do it. No matter how well behaved, nineteen animals is still nineteen animals. While I appreciate that pet owners can be very responsible (see self), I also know that my four dogs, three cats, and one rabbit do take a toll in wear and tear on a house and yard. Double that and then add THREE more on top of the DOUBLING of my own crew, and, yeah.
Or rather, NOPE.
