Reptiles are popular pets around the world, although their welfare requirements in captivity are not always met, due in part to an apparent lack of awareness of their needs. Herein, we searched a selection of the scientific literature for evidence of, and explorations into, reptile sentience. We used these findings to highlight: (1) how reptiles are recognised as being capable of a range of feelings; (2) what implications this has for the pet trade; and (3) what future research is needed to help maximise their captive welfare. We found 37 studies that assumed reptiles to be capable of the following emotions and states; anxiety, stress, distress, excitement, fear, frustration, pain, and suffering. We also found four articles that explored and found evidence for the capacity of reptiles to feel pleasure, emotion, and anxiety. These findings have direct implications for how reptiles are treated in captivity, as a better understanding of their sentience is critical in providing them with the best quality of life possible.
