He will be bigger than Zoey before you know it.
He's gorgeous Sicy.
When Zoe started getting bigger, Stussy started really looking older and thus a bit smaller (old cat sag etc). There was a period of a few months where from a distance, it really was hard to tell the difference between them. I'd call one of them and start yelling that they were ignoring me then realise it wasn't the one I had been calling to.
I wonder if you will get that too. It makes me wonder how breeders cope lol.
