Do you have a couple of chairs that aren't in the greatest shape any more? Have you found some interesting chairs at a yard sale? Here's a really neat way to put some old chairs to use. Of course, your animals would have to be of a certain size to be able to actually use these food/water bowls.
I like this idea because it gives some character to the pet's bowls. Rather than have them on the floor where they are constantly stepped on/in or knocked over, make them a part of the decor.
