The plot may require it, but it does happen in fact.

Animal inheritance has been popping up in recent years, and people have gradually become accustomed to it. The fast pace of life and indifferent interpersonal relationships have left many people with nowhere to relieve their loneliness and no spiritual sustenance. Some people instead regard pets as their "companions", their "sons" or "grandsons". For pets that have spent countless days and nights with them, owners also hope that they can continue to live a worry-free life after their death.

Currently, the second-ranked gorilla on the list of richest people in the animal world is a gorilla named "Kalu". The owner of "Kalu" is Patricia, the ex-wife of Australian swimming star Frank O'Neill and the daughter of the Earl of Kenmore. Patricia found "Kalu" tied up in a tree in front of the Argentine Consulate in the Democratic Republic of the Congo, so she rescued him and took him back to his home in South Africa to raise him. A few years ago, Patricia passed away and left "Kalu" an inheritance of approximately US$62.63 million (approximately RMB 400 million).

There is such a rich cat in Italy. Maria Assunta, owner of Italian cat Tomasino, dies. In her will, Maria stated that she would leave all her property of approximately US$15.66 million (approximately RMB 100 million) to her beloved pet cat "Tommasino". "Tomassino" became rich overnight and became one of the richest people in the animal world.
