You guys are good at coming up with stuff. I thought I would ask. I
thought a hi tech thing to do would be to install some sort of motion
detection valve that would briefly open when motion is sensed and would be
connected to an air tank to "blow" at the cat, however this is probaly too
expensive and I know of no motion detedction valves that would perform
this way.


I could do that with all off the shelf components, and not very expensively
either... or do you mean free and have me do all the detailed design work
for you?
