For everyone who asked, yes I still have her. And no its 100 percent her. She ran up to me when I was walking in the door. I was so shocked I didn't believe it. I was like this has to be another cat. I didn't even let her in at first. I texted the new owner and asked if she had my cat. She claimed yes. Wasn't sure if she was telling the truth.
So I go outside and I called her name and she ran up to the door and ran in. She acted like she had never left. She jumped on top of the counter as she always did to be closer to my face. She jumped down and started clawing her old spot. On my couch
So I texted the new owner and was like um this is my cat 100 percent. She never replied again. So I went to the store and got her food and litter again.
She just had 6 kittens a couple of weeks ago. Gotta get her fixed. But yea I have no idea how she found her way back to me.
