Do cat repellents work? How to stop a cat from using garden as litterbox? Tell me how to keep cats out of my garden. These are common questions of concern to all gardeners but is there a real answer?
The first line of defence is to ensure that your yard boundaries are secure. Any gaps in your fence should be blocked to deny low level access. But cats can jump so fix a taut wire or string some six inches above the top of your fence to deter this approach.
Once inside your garden many people say that the best cat repellent is a dog who will soon see off any feline invader. If you are not a dog lover then you will have to resort to more passive methods. Since cats like to lie on freshly dug soil you should lay mulch on your borders so that no bare soil is left exposed. Seed beds should be covered with wire netting or twigs arranged as a barrier.
Young trees should have plastic guards fitted around their trunks to protect them against use as a scratching pole.
