rats stocking our German shepherd

noticed our big girl doing a plop, where she wants something she will just drop herself down a level vs climbing down so had to see what was afoot as the cage was just cleaned. turns out she wanted to get the puppy's ear for idk why but she sure does try, even enlisted help from her sister. it's kinda long at almost 10 min but it's kinda cool, rats are pretty strange lil critters
