Keeping pet snakes can be ethical as long as their care requirements are well understood and met. It is important for snake owners to provide a suitable environment, proper nutrition, veterinary care when needed, and ensure they are kept in conditions that promote their physical and mental well-being. It is also crucial to source snakes ethically, avoiding wild-caught specimens and supporting reputable breeders. As with any pet ownership, responsible and informed care is key to ensuring the ethical treatment of pet snakes.
