@futurebird we used to have a cat, Lygar, he killed small lizards but one day I found him basking next to a full-grown (25-30cm) Bluetongue lizard on the paving out front. I surmise the Bluetongue probably hissed defensively on approach, Lygar would have backed off saying "gotcha bro, how about we just catch some rays together" and they would have got on fine from there.
