I certainly won't use the cayenne pepper if it will harm the cats. I can't use the mothballs because they will harm my breathing. I'd like to try the citrus, but I sure don't want the opossums and armadillos to come here. The water guns sound ok, but you have to be outside to catch the cats in the act. I suppose we may have to resort to the cages since I called the animal control for information on what to do about the cats and that is what they said the use. Maybe if I put out a sign saying we are using them, the neighbors will be forewarned and keep their cats home. Of course the cats may be coming here from other streets in the subdivision and the owners won't see the sign. Oh well. Thanks again for your kind help. :) A big thank you to those of you who are responsible cat owners and respect the rights of others. :)
