You want a beautiful home with thriving houseplants, but your cat is a plant-eater or your dog investigates everything with his mouth. So you've resigned yourself to an all-plastic, all-plastic aesthetic. Stop. You don't have to choose between plants and pets.
After years of helping pet owners create plant-filled homes without sacrificing safety, I've discovered that plenty of gorgeous plants are completely safe for curious cats and adventurous dogs. The key is knowing which ones are safe and setting up your space thoughtfully to prevent problems.
Understanding Plant Toxicity
Before listing safe plants, let's understand how plant toxicity works:
Most houseplants cause mild to moderate gastrointestinal upset if ingestedโvomiting, diarrhea, drooling. A dog munching a few leaves of a mildly toxic plant usually recovers fine with minimal treatment.
However, some plants are genuinely dangerous and can cause serious organ damage or death. These include:
- Lilies: Cause fatal kidney failure in cats (extremely toxic)
- Dieffenbachia: Causes severe oral irritation
- Oleander: Causes cardiac damage
- Sago palm: Causes liver failure
- Yew: Causes cardiac arrest
The ASPCA maintains a comprehensive list of toxic and non-toxic plants available on their website.

Best Pet-Safe Plants for Cats
Cats are curious and often explore plants orally, so safety is paramount.
Spider plant (Chlorophytum comosum): This is perhaps the most cat-safe plant. It's completely non-toxic, grows easily, and is nearly impossible to kill. Interestingly, many cats are attracted to itโsome sources suggest it might have mild catnip-like effects. Hang it high or in a protected spot since cats love to chew the dangling leaves.
Boston fern (Nephrolepis exaltata): Safe for cats, though some cats enjoy destroying the delicate fronds. Provide sturdy placement away from cat traffic. Requires moderate humidity and indirect light.
Parlor palm (Chamaedorea elegans): A beautiful, slow-growing palm that's completely safe for cats. Adds tropical vibes and is relatively forgiving of care mistakes.
Calathea varieties: These beautiful, patterned-leaf plants are safe for cats and provide visual interest. They prefer humid environments and indirect light.
African violet (Saintpaulia ionantha): Completely safe, flowers attractively, and prefers indirect light. Keep away from plant-destroying cats as they can be fragile.
Areca palm (Dypsis lutescens): A stunning, tall plant that's safe for cats. Provides height and greenery without toxicity concerns. Grows relatively quickly.
Bamboo palm (Chamaedorea seifrizii): Another safe palm option with delicate, feathery foliage. Requires bright, indirect light.
Marigold (Tagetes): A flowering plant that's completely safe. Blooms cheerfully and can be kept indoors or outdoors.
Best Pet-Safe Plants for Dogs
Dogs are less likely to eat plants than cats, but some are habitual plant-chewers.
Pet grass (cat grass or wheatgrass): This is actually meant for pet consumption. Grow a container specifically for your dog to munch on guilt-free. It provides enrichment and satisfies the plant-eating drive without toxic risk.
Boston fern: Safe and non-toxic, though dogs might find it unappetizing.
Spider plant: Safe for dogs, though they're less interested in it than cats usually are.
Phalaenopsis orchids: Completely safe and beautifully elegant. Most dogs don't find them interesting but they add lovely aesthetics.
Prayer plant (Maranta leuconeura): Safe for dogs, attractive foliage, and relatively undemanding in care.
Ponytail palm (Beaucarnea recurvata): An unusual, interesting plant that's completely safe. Very drought-tolerant and requires minimal watering.
Air plants (Tillandsia): These require no soil and are mounted on decorative pieces. Completely safe and add unique visual interest. They're less likely to be eaten since they're typically not positioned within easy reach.
Creating a Pet-Safe Plant Display
Even with safe plants, strategic placement matters:
Hang plants high: Use hanging baskets or wall-mounted shelves to keep plants away from pet reach, particularly for curious cats.
Use plant stands: Elevate plants on sturdy stands that won't tip if a pet brushes against them.
Barrier method: Use baby gates or furniture arrangement to create plant-only zones your pet doesn't access.
Combination approach: Mix safe plants at pet level with higher plants on shelves. This provides greenery throughout your home while managing safety.
Regular monitoring: Watch how your pet interacts with plants. If a particular cat shows excessive interest in destroying a plant, move it to an inaccessible location.
What to Avoid
Never bring these plants into homes with pets:
- Lilies: Extremely toxic to cats; can cause fatal kidney failure
- Dieffenbachia: Causes severe mouth irritation and distress
- Philodendron: Similar to dieffenbachia; causes mouth irritation
- Oleander: Cardiac toxin
- Sago palm: Liver failure
- Foxglove: Cardiac toxin
- Daffodil and narcissus: Gastrointestinal and cardiac toxins
- Poinsettia: Mildly toxic; causes gastrointestinal upset
- Azalea and rhododendron: Cause gastrointestinal and cardiac symptoms
Many of these are beautiful plants, which is tragic. But the risk isn't worth it, particularly for highly toxic plants like lilies.
Pet-Eating Plant Behavior
Some pets are obsessed with eating plants. This isn't necessarily a sign of illness (though sometimes it indicates boredom, stress, or nutritional deficiency).
If your pet is a habitual plant-eater:
- Provide pet grass as an outlet for this behavior
- Redirect to appropriate toys and activities
- Ensure adequate enrichment and play
- Remove or securely restrict access to all plants, even "safe" ones (consuming quantity matters)
- Discuss with your veterinarian whether the behavior indicates underlying issues
Maintenance and Safety
When maintaining your plants:
- Don't use pesticides: Pesticides are toxic to pets. Use pet-safe alternatives (neem oil, insecticidal soap)
- Avoid fertilizer chemicals: Choose organic fertilizers or pet-safe options
- Keep soil accessible: Soil from pots isn't inherently toxic but can contain mold or fungi. Prevent pets from digging in soil.
- Prevent water accumulation: Standing water in plant saucers can harbor parasites. Empty regularly.
- Clean leaves gently: Use water onlyโno commercial leaf-shine products
Plant Sources and Selection
When shopping for houseplants:
- Verify safety: Before purchase, verify the plant is safe for your specific pets
- Check the ASPCA list: The ASPCA Animal Poison Control Center maintains a searchable list of toxic and non-toxic plants
- Ask nursery staff: Most can advise on pet safety
- Buy healthy specimens: Healthy plants are less likely to have pest issues requiring chemical treatment
The Role of Enrichment
Beyond safety, plants provide environmental enrichment. They improve air quality, provide visual interest, and can satisfy your pet's curiosity (especially cats). Creating a plant-filled environment while maintaining safety is entirely possible.
Combining Plants and Pets Successfully
The plants above are tested, proven safe for pets. By choosing from this list and managing placement thoughtfully, you can create a beautiful, plant-filled home without worry.
Some of the most successful pet-friendly homes I've seen use a combination approach: spider plants and safe plants at pet level, higher shelves with additional plants out of reach, and designated pet grass specifically for plant-eating behaviors.
Your home can be beautiful, green, and completely safe for your curious cat or investigative dog. It just requires thoughtful selection and strategic placement.
