Well you can always sell them. I remember once, years back, when i was still in the army, one of the guys in my unit found a pair of Dachshunds. They were so cute and we all played with them for a few hours. Then a bunch of Thai workers from a nearby construction site wanted to buy them. We saw easy money and so we sold them to those Thai workers.
Later that evening, several of the prowler patrols around the camp reported back in, that they smelled something very fragrant coming from the Thai work camp nearby.
