If you pass away in your home and you have a pet cat, it will eat some of your corpse if you're not discovered. Your cat will jump on your chest because they can hear your heart beating and they can tell when it stops. They can also hear you breathing so if you stop breathing, the cat will know because their hearing is much better than ours and they can hear all your body functions. This information is confirmed by police officers that respond to discoveries of bodies in their homes, they have small portions of their bodies consumed by their cat.
The good news is you won't care because you're not alive. It's not an act of malice, it is just the cat feeling hungry and eating to stay alive: the cat wants to survive. It would also help with the smell because there would be less rotting body mass.
