It is so very sad when pets outlive their owners. /S
I saw your sarc tag. :)
However, in all seriousness just let me add this. Humphrey the hippo was six years old when he savagely bit and pummeled his owner to death. Frankly, I am amazed the man survived the hippo as long as he did. As soon as Humphrey matured into an adult male was the time to send him packing. The hippo is the most deadly animal in Africa. Even for a wild animal ‘pet,’ the man was pushing the envelope.
