Thank you for your question. I've posted a lot of ways to deter cats
from coming into your yard.
"- Scatter pinecones in the areas the cats like to visit, especially
under bushes. Ponderosa or other prickly cones work best.
- Buy a commercial cat repellent and scatter or spray it in the
places where the cats are doing their business.
- Sprinkle heavy coats of pepper in those areas (I use about one
4-ounce can) where they are leaving their calling cards."
"got a motion sensor sprinkler and the cats were gone in 3 days. I
couldn't recommend it enough. We move the sprinkler around our yard
every few months to keep the cats on their toes but, in general, the
cats don't come around. The one we got was a scarecrow from
www.frontgate.com and cost about $ 100 (you could probably find
something cheaper if you shopped around)."
"discouraging cats from using the garden as a litter box. I've found
that plastic forks stuck into the ground with the tongs up are very
effective because cats find it impossible to dig around them. Also
I've heard that cats dislike walking on aluminum foil. The best
permanent solution is to plant something thick where the cats usually
dig, possibly something low-maintainence and drought-resistant. Use
the plasic fork plan while the plants are becoming established. You
didn't say if the cats are your pets, so I don't know if you're trying
to banish them from your garden or just preventing them from using it
as a sandbox. If you want them out of the garden all together you can
purchase a motion sensor sprinkler that will startle them away. Pepper
powders, as you've found, don't always work. They can also be harmful
to a cat, especially if it gets in a cat's eyes."
"To the person who wanted help with cats pooping: we've used chili
pepper flakes successfully in our backyard. The drawbacks are that you
have to put it out every coouple of days and that you have to wait
until your child doesn't eat everything she comes in contact with.
Also, I've seen machines in catalogs that emit sounds that cats, dogs,
mice etc get annoyed by. I've never seen them in stores though."
"A few years back Times columnist Gary Bogue had advice about putting
a wobbly fence on top of your fence to keep out cats."
"One way to keep the cats out is to put down chicken wire. Apparently,
they hate walking on it."
