How to read a status
- Known hazard — a reliable source lists the plant as toxic or clinically concerning for cats. Keep it out of the catio and out of reach.
- Conflicting evidence — sources disagree. Treat with caution.
- Insufficient data — not enough information. Not recommended where cats can chew it.
- No known issue found — not listed as a hazard in the sources reviewed. Not a guarantee: any plant can upset a cat’s stomach, and fertilisers, pesticides and soil additives are hazards of their own.
