I fed a stray cat every day.
Then the cat started to place a dead insect or bird at the entrance of my house.
She wanted me to eat the carcasses, which seemed to be a token of gratitude.
After that, the cat passed away, making me feel lonely.
But dead insects and birds continued to be placed at the entrance as before.
I felt this strange so I watched the entrance. Then another cat came to my house to put a dead insect at the entrance.
It seemed that the new cat wanted me to feed her.
So I feed the new cat now.
