So apprently, it wasn't................ It's for us to drink drink from it. Our fountain is filled up with Diamond Water.
Read more bout it @: DRINKWELL PET FOUNTAIN
It looks bit scary.........i dunno when i'll get used to drinkin from there......... its like a big home-waterfall.
(M: Because stagnant water tends to have build-ups of bacteria, this is a better choice as water is always bein filtered constantly, providin fresh & coolin water. Yes, I even drank from it myself. Altho' we were already usin filtered water (on their yogi bowl) before. This holds bout 8litres of water in the "reservoir" @ the back. Thus, I'd only need to refill water prolly like once every week or so. & no, I didn't import it, I got it thru a friend... who sold it to me @ a much cheaper price..... Ok, i've gotta go teach the bitches how to drink from it now... ;p )
Another good water fountain is Dogit (for large dogs)
Update (2011) :
Our Drinkwell fountain's still working very well after four years.
