Our neighbors recently moved away and took their cats with them. They used to be really territorial and kept Tom and his boys away from our garden. But now word has gone out and Tom cat and the boys have left lovely "presents" for us to trod on. Very unique experience when trying to rush to work or better yet kids running in doors and jumping on the sofa with shoes. After having a family meeting our Guinea pigs expressed a strong feeling of resentment towards tom and the boys. Is there such a thing as a Cat repellent anyone can recommend?
