Happy cats have clean water and no gross slime mold.

My cats are enjoying it.

These filters work great they keep the water clear of the nasty tastes in the water my cat likes the water a lot better.

Cat doesn't like the taste of the charcoal

My other cat though, he's stubborn, lol

My cat also likes to rinse his paw in the moving water so this filter is a must have for me

Cats in the wild don't drink much water because they get their fluid from a fresh kill (hey, they are descendants of lions!), but cats who've learned to live indoors must have a clean adequate supply of water near their food station so they are encouraged to drink

Exactly what we needed.....happy cats!

The cat has only ever drank from this fountain and we often joke what she would do if the power went out for an extended period of time

Not happy with the fountain - it's too weak - poor cat can't drink the water without licking the side, so no amount of filtering is working.

but thing if there was a way to clean water for 2-3 weeks without the "evidence" of the agent, cats would form a 'pride' and flock to it.

Very nice, my 2 cats love it

They fit and work fine (one cat, same filter in for over a month).

My cat got sick after using these filters

Cat and dog love it

My cats love it and the fountain actually keeps water a bit cooler in the summer heat for them

My cat LOVES THIS

The filters were delivered quickly and fit my cat's drinking station well.

How often you clean it will depend on your space and placement as well as how many cats you have

Our cats are spoiled and need filtered water

A necessary product with the Drinkwell fountain, which I love for my cat, and the cat seems to love.

My cats are really enjoying their clean tasting water

Used for my cats drinking fountain and works perfectly to clean the water!

my cat loves his little gift he sit and watch the water run and then drink it.

My cats now prefer -nay- demand a water fountain with filtered water for their thirst quenching needs

so I can keep my cats happy

These seem to keep the water and bowl cleaner longer and actually entice my cats to drink more which is a struggle generally

My cat loves to drink the water and especially loves it after I clean the fountain and change the filter

Our 2 cats just love drinking from our Drinkwell mini.

My cats love the fountain.

This item can't be used because my cat removers the top and tries to eat the filter.

Now we have a bulky water bowl and spoiled cats who just stare at it and refuse to drink if they don't see us pour fresh water in

Cat is super picky about water and will spill it if it’s not fresh, so these have been great and the fact I can cut them to fit our fountain makes saves money!

cat loves his water now

Fit nice and snug, my cats love their waterfall filter.

My cats are so Happy!!

and cat really misses it!!

No fountain would make for a very unhappy cat

cats love them

I normally don't give one or five star reviews unless it's as bad or good as it can possibly be

They work as they should!

Doesn't keep the water as clean as it says

Since this is the only filter that will work with my fountain, I guess it works as it should.

Buy these every few months for my small pet fountain, and they work as they are supposed to

It will sink t the bottom of the bowl and chill there til you clean it out.
