Cloning pets raises ethical concerns related to animal welfare, genetic diversity, and potential psychological impacts on the cloned animals. Some argue that cloning can be seen as a form of exploitation of animals and may not prioritize the well-being of the cloned animal. Additionally, cloning can also have negative effects on the gene pool by reducing genetic diversity. Therefore, many animal welfare organizations and experts discourage the cloning of pets and advocate for other forms of honoring and remembering pets instead.
