Cats just been sick

Hello, might sound rather normal a cat being sick but Dora is 6 months old and this is her first sick time experience.
She has eaten just before she settles in for the night at 1030pm. Dry food drank some water. No change in herself.
Just woke up to 5 piles of cat sick. 2 big dryer piles with undigested food and 2 smaller bile like wet piles.

Seems subdue in herself after being sick which is to be expected but haven't changed the diet she not an over eater. She was outside between hours of 7-8 so worried if she's eaten something.
Any advice?

I would just watch her to make sure she is acting normal after this. She may have over eaten after being outside without food. If she is not eating or acting lathargic I would take her to the vet.

How is Dora now?  Is she still sick, or is everything back to normal?
