Kitten needs a home.

I am needing some help in helping this kitten find a home. Recently I found this kitten on my porch at my apartment and saw it had a collar. So I brought it inside to see if I could help find it's owner. However it turns out it was a flee collar. So that did not help. Calling my apartment office and posting on our apartment page to see if anyone lost a pet did not help either. I also took her to a vet to see if it was chipped but alas was not. She is super friendly and well maintained so I think it was or is someone's pet? But I can't keep her anymore at my apartment as my current cat is super stressed by her presence and is not the best with stress. I have also looked through the Indy lost pets page to see if she is maybe on there but culd not find anything. N If anyone has room for another pet and can help or has advice I would appreciate it as I just can't keep her here to much longer with how my current pet is reacting.
