When I approached my geckos enclosure this afternoon, he exited his hide to greet me. At this time, I was flattening out his mulch substrate and sifting it around. I noticed that this movement had caught his attention, and so I pulled out his feeding tweezers and started moving them around the enclosure, and he proceeded to chase them back and forth. With this being said, it raised my question if whether this was just natural instinct to investigate the object and determine if it was food, or if African fat tails are capable of play. Does anyone have an opinion?
