How Cats Spread Diseases

Some cats look healthy but still have germs. It is important to learn the common ways cats spread diseases.
Bites And Scratches
Cats can bite or scratch when they feel scared or stressed. These wounds may carry bacteria or viruses. If a bite or scratch breaks the skin, germs can enter the body and cause infection.
