We're currently Cat-Sitting for family members, this is Nami! She barks little meows like a dog, and absolutely loves staring out the window all day. :)
One time I heard a duck in the kitchen. Quacking up a storm. Quack quack quack quack quack.
This was quite startling, since I don't have a pet duck, and there's no reason a duck should be in my home.
So I go into the kitchen, and I see no duck. The quacking stopped once I started walking to the kitchen. What I DO see is my sweet little cat. Just staring up at me from the midfle of the kitchen, like "S'up?"
I start looking in cabinets, and closets, inside the oven, behind the fridge. There was no duck. There never was a duck. I eventually begrudgingly accepted that was my cat making duck noises. She hadn't done that in the previous 6 years, and never did it again the rest of her life. And she never had any concept that her making duck noises was weird.
I even checked the windows to see if maybe the duck was outside, the windows were closed. There WAS NO DUCK.
It's been over 20 years. It still messes with me, that there never was any duck. That it was my cat the whole time. She was a sweet cat, who loved everybody.......but I'll never be 100% sure there isn't some duck conspiracy I know nothing about.
But she was a sweet cat.
