Well, usually they prefer not to show them. Nature shows are generally pretty “feel good” kinds of shows.
I have seen dead cubs on nature shows. It’s depressing.
Saw one where a single lion survived while her entire family died, the watching elephant that had trampled them gave her an almost mocking look & she looked embarrassed…it hurt her pride see.
We had a possum get deaded by the garage. Every time I took the trash out I checked his progress. It was pretty rapid. It’s like he just melted into the earth. At the end of 2 months there was no trace of him except bones. One of his bones was exactly the right size I needed to secure the hasp lock on the garage door.
