using yard as bathroom

Question
We have a lot of neighborhood cats who are using my yard and planters as their bathroom.  Some of them  don't even cover it up. How can I stop this?

Answer
Hi Susan,

Cats don't like to step on aluminum foil,  is there anyway you can put that down for awhile until they stop?  Also, moth balls are a good deterrent.  I have even put pine cones in planters because they don't like to step on them.    Hope this helps!

God Bless,
Becky
