I've wanted a raised pet feeder for years, but they are SO expensive ($100-150 for the really nice ones–and the less expensive ones are often MDF). If there's one thing Ana White has taught all of us here, if you want something . . . you can make it yourself! :) I don't use Sketchup and don't have a nice camera, but put the plans on the web:
Mine isn't stained and varnished yet, but I wanted to get the plans online right away for anyone who may want one, too.
The cost (if you have the basics like stain and varnish, and find spindles for as little as I did–$2 each!) can be as little as $20. Plus you can customize the height for your specific pet.
