I see nothing wrong with hybrids in general UNLESS it causes the quality of life of the animal to go down. Bengal and Savannah cats are popular pets and I hope to have a Bengal one day. Beautiful creatures. The cow crosses were a bit strange but as long as the animals were being cared for properly and were not suffering I see no real PROBLEM with it. Weird, yes. Wrong, no. Now if you were to cross two animals and the offspring be suffering from deformities or defects, then I see a problem. As long as these animals are not being released into the wild, I don't have a problem with it, just like people who are breeding different kinds of snakes together.
