I was looking for a raised feeder with a stable base as many are more decorative, but not practical. I got the medium size, 8 in raised; the bowls are standard diameter so I was able to find extra bowls that fit perfectly for cleaning rotation. I like that water spillage is contained in solid feeder bowl slots and does not drain on the floor. I have never used the optional water bottle attachment slot, so I can't comment on its practicality. Mfgr says, "You can also use the optional watering feature of this diner. To use, simply lift out one of the bowls and replace with one of your plastic bottles, filled with water and turned upside down. The feeder has a receptacle to receive the bottle; simply screw it in and you will have a longer-lasting supply of water."
