This is a very difficult question to answer because every cat is different. Some cats will come back quickly, while others may never come back. First, you can consider whether the cat is trained. A cat is more likely to come back if it has been trained before. Training can help a cat understand its owner's voice and also give it a sense of home, making it more likely that it will return home. ​​​​​​​ Secondly, it depends on the age of the cat. If the cat is young, then it is more likely to come back. A young cat is easier to educate and more likely to obey its owner's commands, so it is easier for it to return home. In addition, it also depends on the cat’s personality. Some cats prefer to be alone, and they may not want to go home because they may not want to be around people. On the other hand, some cats may prefer being around people, and they may return home more easily. Finally, it depends on the cat’s health. A cat is more likely to return home if it is in good health. However, if the cat is sick, it may not come home because it may die without knowing it. In short, how long it will take for a stray cat to come back after being lost depends on its training, age, personality and health. There is no definite answer, only the cat himself knows.
