To stop our kitty from
tipping the base:, we used double-stick tape and secured the base to a 12x12 ceramic tile.
We also prevented pulling out the stainless steel tray: used by using small pieces of duct-tape in four places (along edge and down side)
Attaching the base to the tile makes it awkward to clean, but do-able. The tray can’t be moved, so we don’t have to deal with the wet filter being removed and dragged across the room. Only The only thing we can’t prevent is her taking out the flower.
We have two of these fountains, and while these preventative measures make the cleaning inconvenient for us, we will continue to use them until they stop working or until we grow tired of doing this. AA different fountain will be in our future, I’m sure.
