Frank's much more a fan of red/orange/pink. I must look like a tomato!
My russian HAS mistaken green nail polish for something yummy! It doesn't though, and when he does it, it's completely accidental... (I hope )
What if nipping at the color isn't trying to taste it but just their way of saying they like it since they can't tell you any other way or nipping at you is their way of telling you they love you... but what would that leave pooping in the water/food dishes to say? Lol
