What happens if a cat is hungry for two days?

A healthy adult cat usually suffers no great harm from two days without food, but if it also lacks water it may show dehydration, and prolonged starvation can cause fatty liver disease leading to jaundice and eventually affecting other organs, which in severe cases can be fatal. Kittens and sick cats have weaker constitutions and may develop low blood sugar or shock after two days, so they are more at risk; therefore owners should feed cats on a regular schedule..
