Phoebe and Duke used to play a lot when he was younger. They still get along really well, though there are still the occasional times when Duke decides it's kitty chasing time.
Phoebe cannot stand Violet. Poor Vi wants to play with kitty, but she barks at Phoebe too much and so anytime she gets near her, Phoebs starts growling and hissing and smacking Vi upside the head and Vi just lets her and then barks again! LOL
Henry has strange friends. A few of my neighbor's cats give him a wide berth, but he's always been dying to make friends. Then a kitten moved onto the block that showed absolutely no fear, and now they're fast friends. Henry's also buddies with a young horse that lives down the road from us, and would love to be buddies with the nanny goats there too! My birds don't like Henry, but they're not afraid of him, although he loves them to pieces. We keep them separated, but Henry always sidles up to the bird cages and tries to lick the birdies. No matter how many times he's pecked he still tries again to make friends. He play bows at the cages and even brings his toys over!
