*Don't try this at home!*
This is an amazing video of a lion that was bought from a store to be a pet. Thankfully the new owners realized he should be in his own habitat and did what was best for him. This is their story.
Wild animals should NEVER be family pets in my opinion. Taking them from their natual environment is cruel. (not to mention what some people do to get those young animals from their natural wild mothers so they can sell them)
I know it isn't specificly dog related but the video is an excellent example of animals remembering the people they love. (or their memory in general)
I admit it made me cry like a baby.
