My cat follows me everywhere, even to the toilet. Whenever I'm done using the toilet, I flush it and my cat will stand up with his 2 front paws on the seat and watch the water swirl down the drain. As he does this he will cry as he watches, its like he's worried that the water is going away and never coming back. Its quite funny to watch, but I'm curious if anyone else has seen this behavior or know what this behavior may mean. Thanks!
