If you're looking to keep stray cats away, consider using citrus peels like grapefruit rinds or spraying areas with floral water. Cats are known to dislike the strong scent of citrus, making this an effective way to deter them from entering your space.

Effective Ways to Deter Stray Cats
1. Citrus Scents: Cats find the smell of citrus highly unpleasant. Placing large grapefruit peels in areas you want to keep cat-free is a great start.
2. Floral Water and Citrus Sprays: Spraying areas with floral water or diluted citrus juice can discourage cats from returning. They tend to avoid these treated areas due to the strong smells.
3. Plants Cats Dislike: Cats are not fans of certain plants, like lavender and citronella. Planting these or using dried flowers can serve as a natural deterrent.
4. Commercial Cat Repellents: Numerous cat repellent sprays are available, which utilize scents cats find offensive. Spraying these on objects or surfaces around your property can prevent unwanted visits.
5. Ultrasonic Devices: Ultrasonic devices emit high-frequency sounds that humans can’t hear, but cats find unpleasant. Place these devices around your yard for an effective and humane way to repel cats.
Is a Cat Entering Your Home a Good Omen?
If a cat, especially one that belongs to another family, wanders into your home, it is often seen as a positive sign. From a metaphysical perspective, cats are considered a symbol of yin, and because wealth is associated with water, which is also yin, a cat entering your home could signify that good fortune is secretly on its way, especially for business owners. In Feng Shui, cats are associated with the element of wood. A cat entering your home can also symbolize a shift towards positive energy and improved luck.
If a stray cat enters your home, especially if it is pregnant, this may be interpreted as a call for help. If you provide help and care, it's believed the cat’s gratitude might bring unexpected wealth or good fortune later. Taking good care of the cat, in this case, is seen as very auspicious.
