I remember my mother beginning to read “the Velveteen Rabbit” to me, but she didn’t get very far because I grabbed the book from her and threw it across the room.
“Black Beauty” I also found traumatic.
I basically won’t read or watch any animal stories because the animal always dies.
You might not like “Where the Red Fern Grows” then
Food....for thought!
Not always. But animals are not immortal, either, just like people. Charlottes Web was a favorite my daughter when she was six.
