My cat pooped out undigested dry cat food

Hi there. Just this morning, i woke up to find poop on my doorstep (a place she didn't poop on before) and saw a single poop with several bits and pieces of undigested kibbles beside it. I'm quite concerned because this is the first time it's happened to my kitty and also my first time to experience it as a cat owner. I haven't switched cat foods, and she's still eating from the same pack i bought three days ago, so i don't really know what's up. Her poop is also very sticky. I want to point out that she's not on pure dry food diet, i give her wet food alternately with the dry ones. Her behavior seems normal though, i haven't obeserved her 24 hours yet. I'm looking to seek advice from furrents who've had experienced the same and at the same time, also a lil bit of reassurance that nothing's wrong with my kitty. I couldn't reach my vet since he's on vacation (Sundays are mostly nonwork days even for vets in my country,hehe) thanks in advance

Are you sure it was poop? Could it have been a hairball she threw up with bits of food in it? Cat's won't usually poop out in the open, they prefer somewhere soft they can bury their droppings. 

Hairballs look a bit like poop.

I second the hairball. It can look like poop. Undigested food is normal when a hairball is stuck
