I just spent about 30 minutes cleaning out the bathtub. I scrubbed it down with comet and then sprayed our bathmat with tilex and left the room for a couple minutes (cuz it was kinda icky so i figured a few soaking minutes would do it a world of good)
I came back in to find my cat had jumped into the bathtub!!!! (luckily not on the bathmat). I scooped her outta there, rinsed off her paws (just in case) and finished cleaning with the door closed. (yay fumes!)
I came out of the bathroom when finished to find her rolling around and being floppy kitty like I had given her a bowl of catnip ... and she kept trying to get back into the bathroom (which is off limits until everything is dried and re-rinsed just to be safe)
crazy cat.
P.S. the other cat (Kohana) is nowhere to be found...so i guess she doesn't share the same bleach affinity
