Until you run out of grass!!
You don't. The crane fly (daddy long legs) larvae live underground by eating grass roots. The crane fly is totally harmless to humans and is valuable food for birds.
How long it takes a cat to throw up after eating grass can vary quite a bit, depending on things such as how much grass the cat ate and what else was in its stomach. In general, a cat will throw up anywhere from almost immediately to 5 or 10 minutes after eating grass, though that don't always throw up at all.
THEY CAN LIVE 10 days without eating as long as they can drink water :P
Five days

About 6 years

For the rest of its life, as long as it's given water and salt as well. Horses are naturally made to live on grass and hay, and will have no problem living on it for all their lives.
