Cat disease is a viral disease (Toxoplasmosis or Parvovirosis) that causes severe and acute gastrointestinal problems. Many cats die of dehydration. The condition is well preventable by vaccination of the cat. The current vaccines have sometimes been effective for up to three years. In consultation with the veterinarian, a schedule can be arranged up to suit the situation. A cat that is not outdoors and never goes to shows can have longer intervals than show cats (a maximum of two years).
