It's gone black on my computer too, but a couple of evenings ago, their human "dad" brought in a cat and told the puppies to be good or he would take her out. He gave various instructions about not biting her tail, etc., and held the cat on his lap while the puppies investigated. Finally, the cat jumped out of his lap and wandered around the enclosure, seemingly oblivious to the puppies even though they were all over her - very tolerant cat who is obviously used to puppies. She was a black cat who looked just like my cat, Missy. Now my kitties (and their "mom") want a puppy!!
