I watched one of our barn cats pick up a large nail from the floor in his paw and examine it carefully. He held the nail and turned it over as if thinking “now what can I do with this?”
That was 60 years ago.
My much missed Dusty Springfoot would leave a mouse on my pillow as a gift. Either proof of her job performance or thought I needed a snack.
Many cats actually like to bring “presents” to their owners; it’s a sign of love/affection.
