Hi.  I'm in the early stages of trying to toilet-train my two small
cats.  They kicked some litter out of the box onto the floor, so they
assumed that the litter on the floor was an extension of the litter
box.  The floor, unfortunately, seems to be semi-porous ceramic tile
with lots of grout.  The urine was absorbed and the room smells
abominably.  I put some Nature's Miracle on the area and it was
absorbed too.  The smell has decreased somewhat.  My wife has suggested
squirting the whole area with a thin layer of Nature's Miracle, and
then using a hot damp sponge mop to spread... letting it sit until it's
absorbed and then scrubbing using an ammonia based cleaner and a scrub
brush.  Do you think this will be effective?  Is there something easier
or different I could try?
Thanks,
Elijah
