Anyways, we were discussing this situation not long ago and we agreed that a pressure sensitive plate that turned on a spout would be an ideal solution. A self-serve kitty waterer. Got me thinking and, since my spare time is filled mostly with waiting for Peanut to show up, I started hobbling parts together.
First step was teeing into the nearest water supply:
Finding the right valve took some figuring out. I wanted to stay away from anything electrical. McMaster-Carr had something that looked like it would do the job but they wouldn't ship it to my house. Ended up using a pneumatic valve from good old Princess Auto:
Slapped that on a box and rigged up a wire hoop to support the drinking tube:
And the cats hated it. Wanted nothing to do with it. Crap. Back to the drawing board. Maybe reposition the tube so it's more like a drinking fountain?
The cats remain unimpressed:
Ah well, I'll continue fine tuning. I insist these animals use this thing!
