First question....why would you take your cat in the shower?
Actually, Chi does that thing in the second clip when I try and take a bath. I assume he's warning me it's full of water, but he keeps going for at least five minutes and even when he calms down he sits at the door guarding me...not sure what he thinks is going to happen. The other three walk past him looking at him like he's mad.
And I couldn't leave that clip on long - it was freaking Astryd and Sage out!
