twitch - why would you even take them in the shower if they get freaked out, even if its just in the beginning. That is stress that is not needed. If you want to bond with them then just spend time with them. (outside of the shower) Their is no way that spending time with them in the shower helps you bond better then spending time with them anywhere else. Please stop putting your rats though that stress. As others have stated, you cant be sure that water isnt getting into their ears and that they are not inhaling it too. you just never know. and its better to be safe then sorry.
