I've seen so many posts on this and other forums about how to keep the neighbors cats/dogs out of you flower beds. Cayenne pepper! We have just combined two households. We had 1 dog and 3 cats that were pretty well behaved. Then we added 3 more dogs and 1 cat, put in a doggie door and figured we had it handled. Wrong!! Everyone started "behaving badly. Poop and pee puddles started appearing. Can't identify the culprit...and so on. Garden idea!!! I dug out the Cayenne pepper can and sprinkled a very tiny amount on their favorite places. So far so good! barb
