Perhaps we should try... oops..... (Soory for that way I think, but let's try an "in - mind" experiment" ; Of course if we did this experiment for real, PETA will hack this org....)

Partly inspired by Schrodinger's cat

1) Bury a cat alive, attach cardiograph and brain pulse scan so we can determine when it dead...
2) Bury a cat alive, bring some rotten mice carcass near its head, attach cardiograph and bps too...
3) Repeat the experiment with "pet-O-meter" (I don't know the right name... just some device sold at pet shop to know how did your pet's feel about) attached... look who's sadder
