im sure you have seen the cat water bowls either online or in the store that have running water now these are great but you either need to plug them in or buy batteries.
i was thinking that if we could make one that was a little different lets make it work on solar ... its green and if your on vacation or cant get home you don't have to worry ...
i say this because my kitty has learned to turn on faucets and run my bill up... and he has gotten so spoiled he wont drink standing water.
i was also thinking that we could put a large water reservoir on it( a 2 liter bottle or 2 of backup water) also to save on energy at night when there is no light
i thought we could use a motion sensor so when the cat is in a foot or 2 the water will turn on.
Hope you might find this fun and interesting and maybe ill get to see how you do it so i can replicate the results
have a great day,
John
