One of them was missed.

Great for cat water fountain

Cat was sicker than hell in a week using the fountain these go to. Water was super gross cat barfing everywhere. Common according to the internet-researched after and discovered it’s not just ours. Stick to a good old fashioned bowl.

Fit perfect

These filters are easy to change, and they do work. I was skeptical but then saw after the first use that the filters really do work. Each filter lasts longer if you only have one cat and if you place the water in an out of the way place. With more cats you will need to change it more often. I have one cat and each filter will last for several weeks.

Cats love it!
