It sounds like you've made some good friends with Rocky and Peppi. I'm glad that they were able to share the food peacefully, even though Peppi has a powerful weapon that he could have used against Rocky.
I think it's great that you're letting Peppi stay outdoors. He seems to be a friendly and well-behaved animal, and he's clearly grateful for your kindness. I'm sure he'll continue to be a welcome visitor to your yard.
Thanks @malos10. They are entertaining little critters and I will always look out for them. 😊
