How big is the cat?

He have had a few really cold days! So home ed has been beside the fire. The cat has made his way into just about everything that we've been doing and today he really made sure he was a part of everything. DS6 wanted to know how big the cat was so he jumped up and grabbed my old scale rule from work and started to measure. 

 I don't know that he was at all impressed with his tail being moved about but he was so dozy with the heat of the fire he really didn't care.

 DD9 used her finger to hold the place where the ruler ran out so they could move the ruler up...at Griffin is 85cm long.
