- Ive seen 2 shingleback lizards in our backyard. I dnt knw if theyre a couple or 2 males searchng 4 their mates. Theyve been there loitering every morning for 3 days now. Should i just leave them to roam or should i be concerned with snakes as their predators? Is it also safe to pet them? We've been giving them pieces of bread and so far they‘ve munch on them.
