There are many odors that cats hate, and these odors can be used effectively to repel cats. Here are some smells that cats hate and how to apply them: Citrus scents: such as lemon, orange peel, grapefruit, etc. The sour smell of these fruits is very unpleasant to cats, and citrus peels or squeezed citrus juice can be spread on the area that needs protection to effectively repel cats. Pungent chemical smells: Many chemical cleaners and insecticides have pungent odors that cats don’t like. However, please note that some odors may damage your cat’s sense of smell, so use with caution.

Strong floral scent: The scent of some flowers is too strong and may cause allergic reactions in cats. These plants should be avoided in areas where cats roam.

Mint and Parsley: While many cats enjoy catnip, the strong smell of mint (especially from raw mint leaves) and the smell of parsley can often make cats uncomfortable. You can sprinkle mint leaves or parsley in areas you don't want cats to enter.
