Red-eared sliders and other aquatic turtles are common starter pets whose complex aquatic and basking needs are frequently unmet, resulting in widespread welfare problems including metabolic bone disease and respiratory infection.
Aquatic turtles in inadequate conditions develop progressive, painful skeletal disease and respiratory infection that owners often fail to recognize until severe. The prolonged lifespan means poorly managed turtles suffer for decades. Releases into non-native habitats create ecological harm while the turtle faces an unfamiliar environment with insufficient resources. The combination of complex care requirements and long lifespan makes aquatic turtles unsuitable for most casual pet owners.
