Much better

With the fur baby we have now this type of nozzle for the water to flow from is ok except he knows it isn't what he had so it's taking time for him to adjust. Other kitties of ours would've been playing with the water as it came out. This one is quieter than our old one %26 is a little bigger in quantity it holds. I'd recommend if your cat isn't one who plays in the water. This one also doesn't spill out of the top with the water edge because it is higher than old one we had. No more spills to wipe up or wet floor.

Multipack filter set for silent water fountain

The fountain is so quiet you will not hear anything, and you will need to change out the filters regularly. This multipack makes a good investment for you and your cat. My cat likes the fountain, and I like knowing that his water is refreshing itself constantly.
