That's so sad 😢😢 Here are some tips: 1. Hang lost posters for your cat everywhere in and around your neighbourhood. 2. Sometimes cats go and come back after some months. It happened to me. Just be patient. 3. Put a bowl of food outside everyday. He/She or some other cat might come to eat it. 4. Play 'Noises to call your cat' on KZbin outside. It'll summon a herd of cats, you'll see. It's possible your cat might be gone for good (I've had that experience also). In that case you must get over the depression and try to buy a new one or either try to forget about it by indulging in some entertaining activity. I really hope you find your angel soon ❤❤❤
