I get owning a cat or a dog or even a bird, but never a hamster or rat. They don’t have a conscious. If you placed a perfectly healthy rat in front of a brick of cheese and a dead cow, it would 100% burrow inside the skull of that cow.
Actually, rats are highly intelligent and affectionate creatures. They remember the faces of their owners and look forward to seeing them.
They remember the faces of their owners so they can burrow into them later
