I am trying to decide which to buy for Bijou's car seat the harness or the vest. I think that at almost two pounds a vest might be more secure but I am not sure about the velcro attachment. I am afraid that it would pull her hair and I don't want it to be an unpleasant experience. I think that the vest might be less likey to cause treacha damage just in case she decides to jump. I have been going over this in my mind for weeks and I really need your help.
