Query: I don't spill the water now...

The first two I got of these were used and came with a large cat playpen. Didn't think much of them until I actually needed to use them. I fell in love with them. I like them so much that they are in every crate and playpen and cage that I have. I foster rescued cats and kittens. The way these just set into the slot and then turn to be secure allows me to take out the old water and put in new without spilling. No jerking them from the frame ad the kits can't tip them over! Well designed and easy to clean.
