RE: Does your pet want to join you in the bathroom?
Chipper always follows me into the bathroom, too. At least he doesn't do the "twining around my feet" thing like the cat in the cartoon ! he doesn't like bathrooms since that is where he has to go to get bathed, but, on the other hand, he seems to feel that it is his responsibility to escort me to the bathroom and make sure that I am safe while in there. So, he sits just inside the bathroom door, a good compromise in his eyes. He is doing his protective duty; but can easily make a fast escape should a bath for him look forthcoming.
If I go in any other room, he is always right there, too; since he doesn't have to worry about baths anywhere else.
