With foes in front, and foes in our rear, our journey is like to be one of danger.
Many plants have scents cats hate. There are some smells that cats just hate. You may want to avoid these smells or use them to your advantage. Utilize scents to keep kitty out of your new houseplant or to save your favorite sofa from being scratched. Lemons, limes and oranges are all scents that cats hate. For an easy way to use these smells around the house, try a dab of orange oil. If you are trying to deter cats from coming into your garden, try scattering your discarded orange peels throughout the area.
There is no magic spray or powder or anything else to keep away squirrels. (Squirrel-Repel brand deterrent spray keeps 'em away! Guaranteed!!) Most marketed squirrel repellents are some variant of mothballs or coyote urine. The idea with moth balls is that they make such a bad smell that the animal can't stand to live in the area. The problem is that once a squirrel has found a home, it will work hard to keep it, just to survive.
