Article in English: If cats do not have enough room to move around, scratch, and dig, they will seek another area for a litter box. Insert plant spikes, forks, chopsticks, or similar materials (approximately 10 inches (25 cm) in length) every 8 inches (20 cm) in the soil to thwart cats.  Make sure that the sticks or equivalent materials are inserted to a depth of a few inches into the soil so that they will stay upright. The points on these utensils are not sharp enough to cause any real damage, but they can be enough of a deterrent to discourage your feline friends from lounging about. Lay standard chicken wire (available from hardware stores) down before your plants poke through the soil. Plants can usually grow in between the gaps, but cats will find the texture of the wiring unpleasant to walk on. The chicken wire will be soft enough not to hurt the cats, but strong enough to discourage them from digging in your garden.

As an alternative to chicken wire, you can lay plastic sheeting designed for use in gardens. Lay the lattice fencing over your soil before you even plant your seeds. The gaps in the fencing will make the area unappealing to wandering cats.  Press the lattice fencing into the ground gently so that it is partially covered by the soil. Transplant seedlings and plant seeds into the soil exposed by the gaps of the fencing. Over time, many common garden plants should grow around the fencing without much difficulty. Cats will not like to dig in or play on rough surfaces. You can cover areas of your yard with a thin layer of safe materials like:  Rough-textured mulch Prickly pinecones Pebbles and stones " Scat mats (available at garden supply stores) are plastic mats covered in flexible plastic spikes. The spikes are soft enough not to hurt cats, but they will not like the texture and will keep away.  Depending on the brand, you will usually find the mats in packages of 2 to 5 mats....
