Types

• Carnations are also known by their scientific name Dianththus caryophyllus and are members of the Caryophyllaceae family. These lovely flowers are also known by common names such as wild carnation, pinks and sweet William. Known for their colorful blooms, carnations are used in centerpieces and floral arrangements. Pansies are members of the Violaceae family and are herbaceous perennials. These flowers are easily recognized by their brightly colored blooms in purple, violet, blue and yellow. Pansies are often placed as border plants in flowerbeds and are sometimes used as cake decorations.
  
  

Toxicity

• Although carnations are a favorite flower for many people, cat owners should not place them around their home because they are poisonous. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), carnations contain unknown toxic properties that can cause adverse effects if ingested by cats or dogs. Pansies are another common garden flower, but they are much safer for cat owners to have in and around their home. Pansies are not poisonous and will not produce plant poisoning symptoms if they're ingested by small animals such as cats.
  
  

Symptoms

• Cats that ingest any part of a carnation, including the flower petals, stem and seeds, typically suffer gastrointestinal discomfort, including nausea, vomiting and skin rash. These symptoms are less severe if small amounts are eaten. Pansies will not cause cats to experience symptoms of poisoning, but consuming any plant material can cause cats to suffer from mild stomach upset. Cats may also suffer from an allergic reaction to ingesting plant material. Most allergic reactions in cats are skin-related and cause intense itching. Choking is another common occurrence when cats ingest plant parts.
  
  

Considerations

• If your cat consumes even a small amount of carnations, consult a veterinarian even if no symptoms are present to avoid possible complications. Some plants can cause serious poisoning symptoms that may lead to organ failure or death. It is best to keep flowers and plants out of your cat's reach, especially if your home has young kittens, which are naturally curious.
