Heh, I took a cat litter bucket, the rectangular type, drilled three 1 1/4" holes on each side and two on the ends just a little bit up from the bottom and placed it in a large rectangular cat litter pan. I happened to have a triangular rock that fit well to direct the feed to the holes and weight the bucket down.
The cat litter pan came as a set with two pans, a screen and a deflector so I use the second pan upside down to cover the feeder at night, using the deflector as a protector against other critters coming in to feed at night. It works great and only needs filling about once a week.
For watering I do have a watering jug we purchased but I also took a plastic gallon jug and a plastic planter base and made another watering jug. Drilled a hole in the center of the lid and the planter base and screwed them together with some sealer between the lid and the base.
They do look a sight but they work.
