I have a "Pet Mate"http://www.ferretdepot.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=45249
I absolutely love it. Abby took to it right away. Chynna was freaked out by it and refused to use it until just recently. Now both of them use it.
It's so easy to put together:
1. Stick the adapter to the bottom.
2. Rinse the filter under cold water and drop into the slot
3. Fill up the blue reservoir with water
4. Fill up the white bowl and filter area with water
6. Turn the blue reservoir upside down and put it into the bowl
7. Put on the top
8. Plug in.
So far as cleaning goes, I clean it out once a week with soap and water. It takes me less than 5 minutes total from the time I unplug it to the time I get it refilled and plugged back in.
I had the option of getting this one:http://www.petplanet.co.uk/shop_dev/...r_fountain.jpg
But I decided that it would mean having to clean up a bunch of slimy saliva from them licking the dome.
With the Pet Mate the cat has a choice of drinking from the bowl or from the water flowing down from the filter.
And it's 100% noiseless. The only time it makes noise is when it needs to be replenished with water. The sound it makes then is a soft sucking sound like you get when you try to drink up the dregs from the bottom of a glass with a straw.
