Second One Works Well!
I recently ordered the PetMate fountain because one of my KittenKats had one episode of a urinary problem and I want him to drink more water. After two hours of trying to assemble and get the flow lever to fit the pump; I decided "it's not me" and the part was defective. I called Amazon and was immediately provided a postage-paid return label and confirmation of a replacement. Even with the free shipping option, I received each unit within two days! The replacement was easy to assemble, and I was able to see that yes, the first flow lever was defective. So far, it is working very well and is quiet. I left the flow lever on the "Low" position as recommended and it produces a moderate flow of water down the ramp, creating just a little movement of water in the bowl (which is preferrable to Kitties). I am also very pleased with the long power cord, so the bowl can be placed near their food. Even though they get bottled water, I went ahead and used the carbon filter too. Be sure to rinse it well first. BTW: if you use bottled water, check the label for Magnesium content (magnesium sulfate). Magnesium is the primary mineral found in cat foods that can cause urinary crystals and blockage (a veterinary EMERGENCY that must be treated in less than 24 hours!). I am happy with this purchase, especially for the price and free shipping and great customer care. And kittens are fascinated

Love it!!
I bought this product three or four months ago to stop my cats from drinking out of the toilet/tub after we were done showering. It worked! They immediately stopped drinking out of both of them and instead started drinking out of the fountain.

While I will admit this does take a small amount of maintenance, it is still a wonderful product. Okay, sure, you need to clean it every week or so; but shouldn't you do that with a normal cat bowl anyways? It's just a tad bit harder with this bowl because of the small crevices.

I plugged in the filter on the first day and it was as silent as ever. I couldn't even tell that it was running! I originally was so scared that it was going to be a loud filter, causing my cats to run away from it but boy was I wrong. The filter does need to be cleaned out every now and then from the cat hair and debris, which people have been complaining about. But I would much rather have to clean out the pump every week than have that Cat Hair & Co cycle through my fountain until the water became murky and gross!

My fountain has started to "leak" just recently, but I have yet to determine if that is condensation from the high humidity or actual leaking.

All in all, I love this fountain. Like I put earlier, it does take a small amount of maintenance, but that is understandable.

Great for Cats!
I got this system to be used by my cat and my dog. My dog is only 15 lbs but she quickly drinks the system dry. Sometimes within the same day. I have the standard size. When I got it, there were no other sizes available. My dog also tends to leave debris in the water from her whiskers and beard. It clogs the hole where the water is taken to be recycled through the filter. I decided to put it up out of reach of my dog and use it for just the cat. I have also not been able to find something like Drinkwell's "aqua garden" for the system I currently have.
However, the system is great for my cat. I just wish I could find a cat grass thing for it.

Nice Pet Water
I love this waterer. Believe it or not - it is easier to clean and care for then just a plain bowl of water. I refresh the water every few days and rinse it out. Our water is hard- so this is my second Petmate- and I use bottled drinking water exclusively- no lime buildup in this one! It is nearly silent- and my cat loves it- he drinks more water than he ever used to. He never drank out of the bowl anyway- he would jump in the sink to drink tap water- this makes him nearly as happy- and he can play in it a little... I highly recommend it. His first Petmate I got second hand- but it built up with lime and then the motor died- hence the reason for bottled water only in this new one. It makes a HUGE difference.

Good fountain!
This is my second fountain from Petmate. I ordered the same model because it was only through my own fault that the first one stopped working. I am very pleased with it's design and longevity. I think it's one of the least expensive models. It wouldn't be good for large dogs.
