Amazingly, though, the lucky pair survived the ordeal thanks to their vast bulk - the result of being massively overfed.
Police found the fat felines after reports of a smell coming from their elderly owner's home in Walsall, West Midlands.
Both cats were close to death, but had clung on despite having no access to food.
When officers found the pair they still tipped the scales at over nine kilos - more than twice the weight of a normal cat.
RSPCA inspectors believe the cats - aged around 18 months and three years - managed to stay alive because of their departed owner’s feeding habits, and could have been even heavier before they were discovered.
