How can a cat be trained to push a bottle back onto a table?

To train a cat to push a bottle back onto a table, you can use positive reinforcement techniques such as giving treats or praise when the cat successfully pushes the bottle. Start by placing the bottle on the floor and encouraging the cat to interact with it. Gradually move the bottle closer to the table and continue to reward the cat for pushing it. With patience and consistency, the cat can learn to push the bottle back onto the table.
