Rex is very picky finding the right place to do it. He chooses the discreetest places: high grass, under bush, very hidden places, when possible. He hates to do it on sidewalks or asphalt. He also takes a long time, sniffing the ground in circles, trying to find the right spot.

A few days ago, an old lady complimented me because he never pees on her building front wall, i replied the he is very picky when choosing his toilet.
