Help! Feral escaped her crate

My aunt has a community of cats that live under her porch that she feeds several times a day.  So when my mom and said we wanted a kitten, she was happy to catch one for us.

We caught the kitten in a vinyl crate. Initially, she freaked out and yowled, but after the car ride, she calmed down enough for me to put in a bed, food and litter pan.  In the middle of the night, the kitten manipulated the zipper, opened the crate, and broke free.  She had liter in her food and water.  There were clumps in the box, and moisture under her bed but I'm not sure what was water and what was urine.

Now she's wedged between the couch and where we store our christmas tree, staring steadily at the door to the apartment vestibule.

My mom and I live in a tiny apartment, so there really isn't a room where we can give her to free roam.

I put down food for her, but she dashed to another corner after I moved away.

This is our first cat, period.  We're a little worried that the kitten is too old be be acclimated to a life with us at 3-4 mo of age. Granted we only had her for a day. 

Any advice would be well received.

Ideally if she was a true feral, under eight weeks would have been easier, but honestly, a day is absolutely nothing!  I'm not an authority on this at all.. just wanted to say 'hang in there' and hopefully someone who can help more will be along soon.

In the meantime, here are some threads on the subject:

Welcome to TCS!

The first step is to get the kitten to the vet.  She will need to be checked for cat diseases, vaccines as well as getting dewormed.  I would be certain she is full of worms.  You do not want to deal with this inside your home.  Also if she is 8-10 weeks old, she is nearing the time when she can be spayed.  I am hoping you are planning to spay her. 

Ideally she needs a small space of her own right now.  This will help her to adjust without overwhelming her as well as you not having to cat proof your entire apartment.  You can even use the bathroom if needed.  Just be sure to cat proof everything.  Get on the floor at her level and see where she might hide or what you might get into.  You will need to get a more secure carrier so that she is safe when you are not home. 

Here is a three part video series on working with feral kittens.  It starts with their rescues and then moves to the socialization.  It has lots of great tips.
