Years ago, whilst working in South Africa, I invited my family over for a holiday on safari. It was good, we had two weeks in the Kruger National Park.
Whilst there are a lot of dangerous wild animals in the Kruger Park, the likelihood of coming across them if you are not actually actively looking for them is is vanishingly small.
Nonetheless, one day it happened. My mother-in-law got separated from us and found herself about 100 yards away in a grassy area, and as we looked around to see where she was we saw a lion sneaking up on her.
What to do? I had no idea.
In the end I decided that the lion would have to take what was coming to it, endangered species or not.
No; lions are wild animals. Though they can be very calm they are still wild and act wild. This is why lions and all big cats should NOT be kept as pets. People get them as pets and when they start acting the wild animals they are people don't like it. Also it's cruel to keep them in captivity.
