Query: Great! Mine is 5+ yrs old

I upgraded to the Big Dog when my Golden Retriever kept drinking out of the cat's pet fountain and slurped water got all over the floor. I have had no problems with the fountain. The rubber feet are long gone, but that has nothing to do with how well it works. I have 3 cats and two dogs and all use this wonderful pet accessory.
