One of my old cats once caught a pigeon and left it nicely placed in a cardboard box ready for me to find in the morning. It was so odd, my cat flap is in the chimney breast of an upstairs bedroom, so he either caught the pigeon on the extension roof, pulled it through the cat flap, down the stairs and into the cardboard box under the coffee table, or he caught it in the garden, jumped up a four ft wall with his prize and then went along the roof etc.
I came down in the morning, sat down with my coffee and accidentally nudged the cardboard box with my foot. I thoughts it felt a bit heavy so pulled it out and there was a dead pigeon, flat on its back, like a funeral director had laid him out to rest.
He was an amazing cat. He bought home many strange things, left over roast potatoes, a banana, a hard ball that would have been too big for his mouth. He also broke into a neighbour's house, clawed open her fridge, and she came home to find this random cat eating the chicken she'd left in the fridge 😳
