I was away for a couple of weeks and when I saw her last night on my porch I went and bought food for it (gobbled up in minutes!).
Thankfully a friend of mine is lending me her car so I can bring it to the Humane Society. I'm hoping it's microchipped and they will find the owner. If not, I will adopt it. I can't believe someone would just abandon it.
I've had many cats that have lived to their 20s so she'll be in good hands
