L.B.M. for "Litter Box Marauder", trust me it will fit as the years go on. 
That said I named my cat of 18 years (who recently died) "Itso" which was short for "It So Cute" because when she (it was a girl) was a kitten we couldn't think of what to name her and we were always talking about how cute she was.
You could also name the cat "Pixel" both a computer referance, and a referance to the old Heinlan book "The Cat Who Walked Through Walls".
