Unfortunately I don' thave much advice - never had this problem - but have you tried the vanilla thing? Put a dab of vanilla on the nape of each of their necks. They will then smell the same and maybe Tinky will get over it. Also, you might want to put some vanilla at the entrance to the garage. It could be that she is continually smelling Macy and the babies and that's what's causing her testiness. Good luck!
