Found (lost?) cat

This cat followed me a few blocks home and is very friendly and vocal which makes me think she’s not a stray. She seems a little skinny and has now just been hanging around my house for ~3 nights. I took her to the fire station to get her chipped and they found one but said they would reach out when they had time, but didn’t take my number so i could return the cat. WCRAS says that they’re at capacity for cats, so I’m hoping to maybe find her owner first.
