Cat-Friendly Garden and Yard: Safe Plants, Fences and Fun

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

A garden can be a wonderful place for cats, with sunshine, scents and things to watch. It can also be a place of risk, from toxic plants and chemicals to cars, predators and fights. With good design, you can give your cat the pleasures of outdoors while limiting the dangers.

Start with safety

• Contain the cat. Many cats are safest in an enclosed space, such as a catio or a cat-proof fenced yard. See how to build a catio.
• Fencing options. Standard fences are easy to climb, so use top extensions angled inward, roller bars that spin when a cat tries to climb, or netting.
• Check gates and gaps.
• ID and microchip. See cat microchipping and identification.
• Supervise outdoor time.

Safe plants

Many plants are safe and useful.

• Catnip and catmint, which many cats enjoy. See is catnip safe for cats.
• Cat grass, such as wheat or oat grass. See how to grow cat grass.
• Valerian, another plant that attracts some cats.
• Herbs, such as basil, thyme, rosemary and dill, usually safe in small amounts.
• Sunflowers, zinnias and snapdragons.
• Bamboo and spider plants.

Check each plant on a reliable list before planting. See cat safe houseplants.

Plants to avoid

• Lilies, deadly even in small amounts. See lilies and cats: why they are deadly.
• Sago palm, oleander, foxglove, azalea, rhododendron, daffodil and tulip bulbs, autumn crocus, yew and castor bean.
• Onions, garlic and chives. See are onions and garlic toxic to cats.
• Mushrooms and fungi.

See toxic houseplants for cats.

Chemical hazards

• Slug and snail bait, which can be deadly.
• Rodenticides.
• Weed killers and fertilizers. Choose pet-safe products and follow instructions.
• Cocoa mulch. Contains theobromine.
• Antifreeze and pool chemicals. See autumn hazards for cats.
• Compost, which can contain mold toxins.

Shade, water and rest

Provide shaded areas with covered spots, a bowl of fresh water, and a comfortable bed or bench. See summer safety for cats. Avoid ponds without covers, and empty paddling pools.

Climbing and play

• Low shelves, logs and platforms for climbing.
• Tunnels and boxes.
• A sandbox for digging, which can help keep cats out of flower beds.
• Hiding places, such as pots on their sides.
• Bird feeders away from where cats can reach, to protect wildlife.

Litter and digging

Cats may use garden beds as a toilet. Provide a sandbox, and cover beds with chicken wire or stones. Clean up feces to prevent toxoplasmosis risk. See toxoplasmosis and cats.

Wildlife

Cats kill many birds and small animals. Reduce harm by keeping cats indoors at dawn and dusk, using enclosures, and giving ample play and food. See why do cats bring dead animals.

Health

Outdoor cats need vaccines and parasite prevention. See cat vaccination schedule, fleas on cats and ticks on cats.

Neighbors

Fence and enclose so that your cat does not wander into neighbors' yards, and be kind to neighbors with garden problems.

Planning the layout

Sketch your garden, and mark where the cat will walk, sit and climb. Place a sunny bench or flat rock for basking and a shady shelter, and leave open lawn for chasing. Add height with a sturdy tree, a wooden post or a covered platform. Plant dense, safe shrubs for cover, and keep thorny plants away from paths. Put bird feeders and ponds well away from where the cat spends time. Check the plan every season, since plants grow and fences age.

Maintenance

Inspect fencing, gates and enclosure netting regularly. Walk the garden before letting the cat out, to look for toxic plants, mushrooms and spilled chemicals. Keep tools and treatments locked away, and clear fallen fruit and nuts.

Seasonal garden tasks

In spring, check for new growth of toxic bulbs such as tulips and daffodils, and plant cat-safe flowers. In summer, provide shade and water, and watch for slug bait and pesticides. In autumn, remove fallen fruit, mushrooms and damp leaf piles. In winter, check for antifreeze spills, and provide a warm, dry shelter if cats go out. Throughout the year, patrol the fence for gaps. Keep a list of your garden plants, along with their safety status, so that you can answer quickly if your vet asks what a cat has eaten.

Involving children

Teach children to keep gates closed and to avoid leaving toys or chemicals in the garden. Let them help build a sandbox or plant cat grass.

When to see a vet

If your cat eats an unknown plant or shows signs of poisoning, go to a vet at once. Use the US vet directory to find a clinic.
