Ben, one of my kitties, loves watching the toilet flush (yeah, he's a weird cat). He always hangs over the lid and looks into the toilet then meows indicating for me to come over and flush it. So I decided today to try something out and he had a blast. I dropped a ping-pong ball in the toilet and he must have spent an hour playing. It was so funny. I took some pictures so as soon as I get my scanner up and working again I'll post them .
