Many cat owners allow their feline companions to roam freely outdoors. Your flower bed, full of soft soil that's easy to dig, may attract an inquisitive cat who's looking for a new litter box. A digging cat can quickly disrupt your flower bed's appearance and potentially damage your flower plants. Several physical and chemical control methods can help you get rid of such cats in your garden.
Lay wire on the ground surrounding your flower beds. Cats won't like stepping on the wire, according to North Dakota State University. Add to the wire's deterrence factor by spraying it with eucalyptus or anise oil.
Install a motion-activated sprinkler system in the flower bed. Such products, available at many garden stores and nurseries, will trigger a startling jet of water when the cat approaches. This can quickly scare away not just cats, but other wildlife pests like squirrels.
Plant strong-smelling herbs as bordering plants in your flower bed. North Dakota State University recommends lemon thyme, lavender and geraniums to help deter cats.
Create a cat deterrent powder. This is ideal if your flower bed has lots of open dirt areas. Mix five parts flour, three parts dry mustard and two parts cayenne pepper, according to North Dakota State University. Spread the mixture on the surface of any soil in where you don't want cats to dig.
Check your area's leash laws by consulting a regional municipality office. Pet owners who let their cats roam the neighborhood may be fined. This can help encourage your neighbors to keep their cats contained and away from your flower beds and garden.
