There are no laws of gravity for Spider Kitty!

Look! It’s Spider Kitty!

Whoa there! Whoa there, buddy. There are certain laws regarding gravity and you not having wings that need to be addressed. We're sure you get super excited chasing the Mysterious Red Dot but that doesn't mean you can turn our minds inside out running straight up a wall and practically all the way to the ceiling. Do you hear your owner laughing? That's the shocked yet fearful laugh of someone who is never going to be late with your can of cat food again because you just showed her you basically have superpowers. Don't abuse them, Spider cat. With great power comes great responsibility. (Source)
