I'm afraid I must disagree with Catcastle a little bit. Yes, 
Munkustrap is very brave and very serious when it comes to protecting 
the Jellicles. However, I think he really does love Demeter but has 
trouble showing it. In some of the stories I've written about him, he 
has trouble dealing with all the emotion he feels. I think his 
brother is Macavity (the two hate each other!) and his parents are 
Grizabella and Old Deuteronomy. But then again, no one knows for 
sure.
