Indoor plants breathe life into a space, adding beauty, filtering air, and improving mental well-being. But for pet owners, not all greenery is safe. Many popular houseplants are toxic to cats and dogs, posing serious health risks if ingested. That’s why choosing pet-friendly indoor plants is crucial to keep both your home and furry companions healthy.
In this in-depth guide, we’ll cover: the best non-toxic indoor plants, care tips tailored to each plant, common toxic plants to avoid and safety strategies to reduce the risk to curious pets.
Plant Toxicity Symptoms
Many indoor plants contain compounds that can cause vomiting, diarrhoea, organ damage, or worse in cats and dogs. The ASPCA and veterinary experts recommend selecting non-toxic varieties to ensure your pets stay safe, especially if they’re prone to nibbling.
Common symptoms of plant toxicity in pets:
- Drooling
- Vomiting
- Lethargy
- Difficulty breathing
- Seizures (in severe cases)

Frequently Asked Questions (FAQs)
Q: Can I use fertiliser on pet-safe plants?
A: Yes, but always use pet-safe fertilisers and follow application instructions carefully. Avoid over-fertilising or using chemical-based products that may leave residue on leaves or soil that pets might ingest. Organic or natural fertilisers are safer alternatives.
Q: What soil should I use for pet-friendly plants?
A: Use well-draining, nutrient-rich soil suited to the specific plant. Most pet-safe plants thrive in:
- Peat-based potting mix with perlite or coco coir
- Palm or fern soil for tropical species
- African violet soil for flowering houseplants
Avoid soil mixes with added pesticides or slow-release chemical fertilisers unless labelled pet-safe.
Q: Where can I find a complete list of non-toxic plants?
A: The ASPCA (American Society for the Prevention of Cruelty to Animals) offers a searchable list of toxic and non-toxic plants for cats, dogs, and horses. Always consult this list or check with your veterinarian before adding a new plant.
