Why Create an Indoor Garden for Your Cat?
Indoor gardens provide sensory enrichment for cats who lack access to the outdoors. Cats enjoy sniffing, nibbling, and rubbing against plants. Safe greenery can reduce stress, provide dietary fibre, and give cats a more natural-feeling environment.
The RSPCA recommends providing cat grass for indoor cats as it helps with digestion and hairball management, satisfying a natural grazing instinct.
Which Plants Are Safe for Indoor Cats?
- Cat grass (wheatgrass) — Easy to grow, aids digestion, safe to nibble
- Catnip (Nepeta cataria) — Produces euphoric response in 50-70% of cats
- Spider plant (Chlorophytum comosum) — Non-toxic, resilient, and cats love the trailing leaves
- Boston fern (Nephrolepis exaltata) — Non-toxic and adds humidity to dry indoor air
- Parlour palm (Chamaedorea elegans) — Safe and adds a tropical feel
- African violet (Saintpaulia) — Non-toxic and adds colour
- Valerian (Valeriana officinalis) — Stimulating for cats, similar to catnip
- Silver vine (Actinidia polygama) — Strong response in cats, safe to grow indoors
Which Houseplants Are Toxic to Cats?
The following common houseplants are dangerous and should be completely avoided in homes with cats:
- Lilies (Lilium spp.) — Extremely toxic; even small amounts can cause fatal kidney failure
- Aloe vera — Causes vomiting and diarrhoea
- Pothos (Devil’s ivy) — Causes oral irritation and swelling
- Dieffenbachia (Dumb cane) — Causes intense oral pain and drooling
- Snake plant (Sansevieria) — Causes nausea and vomiting
- Peace lily (Spathiphyllum) — Causes oral irritation, drooling, vomiting
- Philodendron — Contains calcium oxalate crystals harmful to cats
If you suspect your cat has ingested a toxic plant, contact your vet immediately. The Cats Protection and ASPCA both maintain comprehensive toxic plant lists.
How Do You Set Up a Cat-Safe Indoor Garden?
- Choose your space — A sunny windowsill, shelving unit, or dedicated corner works well
- Use organic soil — Avoid chemical fertilisers and pesticides that could harm your cat
- Elevate decorative plants — Use hanging planters or high shelves for plants you do not want chewed
- Make a cat grazing station — Place cat grass and catnip at cat height for easy access
- Protect soil — Cover soil with decorative stones to stop cats digging in pots
- Drainage trays — Ensure standing water in trays does not accumulate, as some cats drink from them

Frequently Asked Questions
Is cat grass the same as lawn grass?
No. Cat grass typically refers to wheatgrass, barley grass, or oat grass grown specifically for cats. Lawn grass may contain pesticides and is not suitable.
Can cats eat spider plants?
Spider plants are non-toxic to cats. Some cats enjoy chewing the leaves, which may cause mild stomach upset but is not dangerous.
How do I stop my cat eating my houseplants?
Provide appealing alternatives like cat grass and catnip. Use citrus-scented sprays on plants you want to protect, as most cats dislike citrus. Move toxic plants out of reach entirely.
Are essential oils safe for cats in an indoor garden?
No. Many essential oils are toxic to cats. Avoid using them near indoor gardens or in diffusers in rooms your cat frequents.
How often should I replace cat grass?
Cat grass typically lasts 2-3 weeks before it starts to yellow. Keep a rotation of pots growing so fresh grass is always available.
