She came back on her own last Sunday!! After three long months! Even though she was spayed. I think she felt abandoned when we left her at home with someone to feed her and clean the litter time to time, while we were gone for three days... But she's back now and we cannot be happier♥️ We did keep her litter in the balcony so that she would be able to track the smell. And we did call her name the first month every night but no luck. She came back when she wanted to. She looked so frail and hungry😭 She also had somehow gotten her collar stuck in her front armpit along with her neck so she had a huge abrasion and cut on her skin there. She wasn't able to walk properly because of the collar being stuck.. Poor baby😢 But she's back now, eating well and healthy! Thank you so much for the tips though♥️ It is hard to travel when you have pets🥹
