Yes, Tilex has a high bleach content (that’s what my nose tells me) and I really spray it down good and wash it out with hot water afterward. I just don’t know WHAT gets into my dogs’ water dishes and just can’t afford to take the chance.
My cats often get into the bunny xpen just to try and drink from the water dish, so I stopped using the dish and set the sippy bottle on the side instead. I know the cats won’t use that. (Sadly, sometimes the bunnies won’t either…kind of the same way that Mimzy wouldn’t use the litter box in the xpen and would only use the one in his night pen…picky things.)
Personally, Tucker, my dogs are way too big to have anywhere near my bunnies, so I can’t speak to the mutual watering hole, but I would think that Katnip answered the question pretty well.
If any of the forum leaders would like to chime in, I’m all ears. ^_^ (Not difficult to be all ears on a bunny site. xD )
