Behold: this is what feline ADHD looks like. Or maybe it's too much catnip. Either way, we agree with this cat's owner in that she's completely nuts.
Most pet cats have one or two quirks that make them who they are, be it strange purring, climbing random things, funny walks etc. Turns out this one has all of them. We think it's clear that '7lb nutball' Luna is just trying to prove to her owner that she has what it takes to be a loyal companion.
That or she thinks she's Batman.
