Just in case there's someone out there in blogland who is wanting one of these for their thirsty moggy or small pooch, I have one for sale. Bought to encourage Charlie to drink more water but in reality they prefer eau-de-pond and Muddy Puddle vintages. We've shown them what it's for, tempted them to eat the biscuits in the attached food bowl but, clearly lacking in the 'make your humans happy' stakes the most they have used it for is a water fight. Oh yes, they'll dunk a paw in and scoop water towards the other, no problems there.
It's quiet and soothing so makes a good indoor water feature for stressed cat owners, cools and freshens the water and should be just what every cat wants on a hot day - but my contrary pair don't see it that way.
Comes with the now otherwise not available mat, 4 filters, boxed with instructions, clean and in excellent working condition and selling for considerably less than I paid out for this in the first place. Just click on the picture to go to the listing.
