Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to stop cats from digging in flower beds [title] Squirt lemon juice or scent on your flower bed. [step] Lemon is a citrus fruit, and many cats hate the scent of citrus, and will be instantly repelled by the scent. Lemon zest is better if the flower plants are growing, but lemon juice is perfect if you have fully grown flower plants to dodge.

Ending1: [substeps] Lemon juice may be used to help stop the smell of insects-even harmless insects. Use a spray bottle of lemon-lime water each time your plant or flower is turned in to attract the cat. Ending2: [title] Drizzle orange oil on your flower garden. [step] Again, many cats absolutely hate the scent (and taste! ) of citrus fruits. Ending3: [substeps] If you don't have lemon juice on hand, you can also try putting limes in the flower beds to entice cats to go deeper. [title] Place your flowers near plants that require discouragement. Ending4: [title] Spray manure on your flower beds. [step] If your garden holds animal-owned manure, feed these manure to your pet instead of digging up and watering as you go about your garden.
