Zap is Zip's brother. The only resemblence being their rather large ears, beyond that, not much else. Zap is very mellow. I love how when I reach to pat his head, he closes his big green eyes, leaning into my hand. It is the sweetest thing. He is very quiet & shy, a bit like his new sister, Katrina. He's a big, beautiful boy who is very loving & gentle. He is so patient to put up with Ringo following him around all the time!
