Missing pet donkey found five years later

[Catherine]

Diesel the donkey went missing on a family camping trip five years ago. He was finally spotted living with a herd of elk. He looks well and happy and the family is going to let him stay with the elk.

It is an odd situation. He is a pet and he should be rescued. However, he seems to have found a life that works for him.
I never thought of a donkey and elk getting along, but it seems to be working.

Maybe they could visit Diesel and let him make the choice. If he comes to them it might be a sign that he wants to be rescue. If he ignores them, then let him stay with his elk friends.
