Thanks everyone!
And on grouting, Pablo doesnt use his tank to go to the restroom, he goes during his baths. I had loose tiles before and it was a pain lifting them out to clean, etc bc if I just sprayed in there it'd get wet under the tiles. If he pooped in there, it'd be a different story. But now I just vacuum it, give it a quick wipe out and its good to go!
