I've never seen a 12g long before - I really love the shape of it. The strong horizontal shape has so much potential. I think you scaped this one very nicely - the quiet open area, the ceramic rock caves, and the pennywort are my favorite bits!
Your cats is super cute, Abysinnians were my mother's favorite breed and I wish she had been able to get one!
Is yours a blue, or was that an effect of the lighting?
