Animals WERE harmed in the making of this caption

Kevin had been experimenting with the technology to swap brains. He had run the test on the household pets and successfully swapped the cat with the dog. Unfortunately, because of a miscalculation, the experiment also resulted in a brain swap between Kevin and his wife, Karen. He ran tests on both himself, his wife, and their pets--all appeared to be healthy. However, when he tried to swap the dog and cat back to their own bodies, they both died. He kept trying with other animals, and while the initial swap was always successful; the swap back always seemed to kill the animals. As he was bringing another dog from the shelter for further testing, Karen asked what he was doing. When Kevin explained the problem, she was horrified and insisted that he stopped the test immediately. She didn't care if they were stuck as each other forever, she didn't want him harming any more animals!
