Cows do not answer to yoo-hoo, hey cow or kissy face noises.
I should know, I tried to get this cow to look at me the entire time while painting. When I realized the racket I was making, I decided to keep quiet so I wouldn't scare the uncooperative things off.
Anyhow, this particular type of cow is very rare. It's part polar-bear, part cow and part Brie, the dog. I had to make up some stuff as I went along, relying on my mental cow library that has seemingly not been updated since I was three.
Other News: I'll be doing a free, live demo of useless cow calls this Saturday at White Magdelena at noon - and I'll paint while I'm there too.
