The European cat snake is venomous, but because it is rear-fanged (fangs are located at the back of the upper jaw), it rarely injects its venom in defensive biting, and is therefore considered no threat to humans. It feeds mainly on geckos and lizards.[citation needed]
The species can be found in open and scrubby country including beaches and open woodlands.[1]
