Frequently asked questions
Are all lilies toxic to cats?
Yes. All types: Asiatic, Oriental, Trumpet — all FATAL. A single pollen grain can cause kidney failure (3-5 days). No lilies with cats.
My cat ate a plant. How quickly to vet?
Immediately (especially Lily). Lily toxicity is time-sensitive: kidney damage happens in hours. Even if cat seems OK.
Are roses safe?
Biologically yes, but garden roses are often sprayed (pesticides = toxic). Organic roses without spray = safer. Leaf carefully.
Cats like to eat grass — is garden grass OK?
Yes. Cat grass (Avena sativa) is specially healthy for cats. Plant this in front garden so cat doesn't go after dangerous plants.
Symptoms of plant poisoning in cats?
- Vomiting
- Diarrhoea/constipation
