Solutions to the problem of a locked up kitten that keeps barking:
1. You can give the cat some toys to divert its attention, and it will gradually calm down.
2. When the cat meows, you can feed it some of its favorite food. With the temptation of delicious food, it will stop meowing.
3. The owner can gently tap the cage to interact and play with the cat. With companionship, the cat will stop meowing all the time.
4. When the cage space is small, the cat feels depressed and will keep barking. You can change the cat to a larger cage with enough space for it to move, and it will calm down.
5. Let the cat out to roam freely for 1-2 hours every day. If you relax, the cat will stop barking.
