He is a great hugge whopping beast of a tomcat. Long and strong and muscular and sportsy.

The Nazgul and I say he's a 'Muskelkater' which is a complicated pun. 'Kater' doesn't just mean 'tomcat', it is also a colloquial expression for hangover. A 'muscle hangover' is the soreness you get in your muscles after working out, especially if you're not used to it. Of course, we use it to mean 'muscular tomcat' when talking of Lucifer.
