"Cat-scratch disease is an infection caused by bacteria or germs, carried in cat saliva. The bacteria can be passed from a cat to a human. Healers and MediWizard Researchers think cats may get the bacteria from fleas, although this hasn't been proved.

"You can get cat-scratch disease from a cat bite or cat scratch. You can get the infection after a cat scratches you if the cat's paws have the bacteria on them. The cat can get the bacteria on its paws when it licks itself. With a cat bite, the cat can pass the bacteria to you in its saliva.

"Cat-scratch disease is not a severe illness in people who are healthy. But it can be a problem in people with weak immune systems.
