My 15 year old cat used to do this for me in her youth. Brought me a big, black, dead rat one morning and put it on the floor by my bed. I was thrilled. She also used to bring me praying Mantis inscects with the heads bitten off.
Screw the “songbirds.” Very glad my Sebastian keeps this a bird-free zone. Also, delivering it to you? She’s definitely concerned that you’re just a big cat who can’t hunt and she’s trying to teach you by giving you an easy one.
