I dont know if you would call it cute, but my leo does this strange thing whenever hes trying to work up a poo lol. He wall climbs the corner of his tank, which is glass so he cant actually climb it, and just stands upright in the corner for 15 to 20 minutes. After a while he gets down, or sometimes he will get down walk around and stand up right multiple times and then finally gets down and does his business. Ive done research on why leos wall climb and most say its because they are in too small of cage, but mine is a 40 gallon breeder tank so its plenty big for him and he only does it in his bathroom corner before going the restroom. So i think he is just trying to get his bowls moving. weird because i havent heard of anything like it before.
