OUR FIRST LITTLE TOOL

The fountain
filter finder.

Your fountain has a model.
Its filter should be a match.

29 supported models and families across Catit, PETLIBRO, PETKIT, Pioneer Pet, and PetSafe. Manufacturer sources, one clear match.

Try “Solo 2”, “6023”, or “Pagoda”.

Find the model name on the base, packaging, or your order confirmation. Similar-looking filters aren’t always compatible.

A NOTE FROM HAPPYCATZ

Life with cats is full of little questions.
We’re here for the practical ones.

We’re building tools that turn scattered product information into something you can actually use. Starting small, checking the details, and being clear when we don’t have an answer.
