off topic.

it's the owners that allow the cats their behavior.

imho, cats train faster than dogs.

cat urine never dries.

wood floors can be sealed with kilz, cheaper than polyurethane and just as effective.

in my job i deal with these issues on a regular basis, too.

i live with four cats - never sealed my floors. we don't have odors.

we now return you to your regularly scheduled topic.
