Only way to keep cats out is to send a message to all the other cats that your not playing around and they will all succumb to the same fate. Hang a dead cat up in the garden, or near it, and put up a sign mentioning don't make the same mistake this cat did, stay out of my garden. Word will get around and you won't have cats anywhere near your garden. Your welcome in advance for this friendly little piece of advice. lol
