Mice are skittish through most of their life, but when they become elderly they suddenly become very keen on getting comfort from their owners. Watch Ruby, an elderly mouse, follow her owner around looking for cuddles.
Younger mice tend to want to live independent lives and are uninterested in human companionship. As they get older, however, it appears as if elderly mice just want to be comforted by their owners and seek them out.
Ruby, for example, was an elderly mouse the family had had for a long while. As she got older, suddenly she started seeking her owners out, looking for food and cuddles.
