This is a wild gecko in Australia that came into someone’s house, as geckos often do, and most emphatically didn’t want to leave. Considering the very small size of this lizard, he puts up quite a tussle. Note the bobbed tail: it probably broke off, some time ago, and didn’t grow back all the way.
BTW, a lot of people like having geckos in their homes. They eat lots and lots of bugs.
In case you thought lizards have no voice, you were wrong. They just don’t feel the need to say much.
