Sorry I didn't notice this earlier, thanks for asking about my boy.
Yes Zaphod is a panther, a Nosy Mitsio. He's a pretty big boy, especially compared to my faly. At the time of this picture last year, he was about 156g, now his most recent weighing had him about 203g. I haven't measured his length in a while, but my last measurement had him at 18 inches long.
