Cat and Pig on National Serpent Day, digital phone drawings, 2/1/19.

Someone asked about Boa Constrictors. They were interested in how to draw them. I have yet to try. 

Boa Constrictors grow up to 13'. They squeeze their prey and swallow it whole - as big as a pig! Skin color depends on habitat. A variety of beautiful patterns mark their skin.

Lots of good info at National Geographic:
