Feline Parvovirus, also known as feline panleukopenia, is a highly contagious viral disease that primarily affects cats. It attacks the rapidly dividing cells in the body, particularly in the intestines, bone marrow, and lymphatic tissues. Symptoms include vomiting, diarrhea, lethargy, and a decrease in white blood cells, which can lead to severe complications. The virus is transmitted through direct contact with an infected cat or contaminated surfaces, food, and water. Vaccination is the most effective way to prevent feline parvovirus, and it is recommended for all kittens and adult cats, especially those in high-risk environments.
