I ordered 2 of these in the largest size thinking they would be ok for cats.  Turns out no, the bowls are way to big it's, it's for bigger animals.  I was only looking at the dimensions of the frame and in particular its height and didn't realize the bowls were so huge.  I ended up gifting both sets to 2 different friends with dogs and they absolutely love it.  These are nice, great quality.  One problem is the bowls go so deep that they aren't going to be the height off of the ground that people expect.  I wish I could order a custom size, the smaller sizes of this aren't high enough.
