I mentioned "Big Honky Duck" before. But I took some pics to show the size...
It's actually a dog toy. But I thought Marley might like it, him being rather large. He was terrified of it. If you squeeze the back, it "honks". So it sat around for years. Lori tapped at it a few times.
Then, suddenly one morning, Honky Duck was in the kitchen. And later in the Living Room. Lori was dragging it around the house! I don't think she actually made it "honk", but she sure wasn't afraid of its size.
You just never know what toy some cat will get interested in!
