I used to put a harness on my first grey (a hyperactive male) and tried it with Chyloe (a calm female) when she was a baby. She tried to bite the stuffing out of me. That was her way of telling me no way no how was she going to wear a harness. Instead I have to use a travel cage to take her places.
