My cat is obsessed with the toilet. She likes to watch it flush (supervised, of course! We keep the lid closed always). She can frequently be seen perched on the back of the toilet bowl. When she is there, she is the unapproachable princess. It is her right to swat over your brush, toothbrush or whatever might be on the adjacent sink. If you dare interfere, be prepared for the silent meow of death, followed by a swat. :p
Her personality does a 180 when she is on her toilet perch.
Does anyone else have experiences like this or is it just our cat? Lol!
