I think I might make some sort of noisy collar, so I can always hear her... she has no inetion of actually hurting the critters her herding insticts is just so strong that she gets wound up and jumps at the cages, she cant touch the bird, I muzzle her now when he is out, and his cage is to high for her to care, the muzzle is just homemade right now, I will be getting her a basket muzzle as she get pretty wound up and works herself into a frenzy when she can barly open her mouth while running back and forth. but I have had to search and gather up way to many rodents lately that she has broken out of their cages.
