Dear Susan:
Well, water alone can do for a few times, but then the dirt is becoming too much for it to handle it.
Of course, a specialty floor cleaner rated for “natural stone” like MB-1 is in order.
“
Is there a product that can be used other than warm water that's safe for animals to walk on/be around?
”
A good-quality stone floor cleaner (not a soap – a detergent!) is not going to stay around for anybody to walk on. Once the floor it's dry, that's it! And besides, since when a floor cleaner residue (if any) has been found hazardous to walk on bare foot (or paws)?? I never even heard of anything like that!

As for the discoloration of the grout, if it became lighter than if was originally there's probably a loss of die and it could be adjusted with specific grout coloring agents. If it has become darker instead, it is dirty and a good tile and grout cleaning agent rated “for natural stone” like MB-2 will do the trick for you.
