Noooo, with a male cat its a BIGGER problem…they spray straight out backwards. I built my big male cat a litter box from a 30-gal Rubbermaid tote to contain his habit of peeing on the basement wall.
The hard part of that trick is throwing all the rocks in a straight line so they LOOK like just one rock skipped 15 times. My kids each fell for it once…
As an engineer I can tell you the EXACT reason there are no flying cars: No matter how idiot-proof something is designed, nature always creates a better idiot.
My big kitty lays like then, and then when I rub his belly he grabs my hand and bites me! Playfully, but even playfully on a cat pushing 20lbs can hurt!
With a long enough schedule and enough budget, R&D Engineers can accomplish ANYTHING!!
