Yes! When our cat Nina was younger, she used to hunt down socks overnight and leave them triumphantly on the foot of the bed.
And I used to have a cat who was totally enchanted by rubber bands. She would hold one end down with her paw, and pull the other end back in her mouth, and then let it fly across the room.
They're all so loony, and all so different. I love them.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
