When do I panic?

[Karcheer]

My cat hasn't been seen since dinner on Saturday, she's a pig and never misses a meal, she's waiting in the kitchen for breakfast and comes and gets me at 5:45 (she eats at 6) in the evenings. She never ventures far from the house, if you walk around the house and call her she'll come. She is however a prolific hunter.

I know it's summer and dry and she is an outside cat.

When is reasonable to start panicking?

Thanks

Is she back yet? They can be such a worry.
