Cats infected with Bartonellosis usually obtain the infection through flea and tick bites from fleas and ticks that are carrying the Bartonella bacteria. While many cats carry the bacteria without showing any symptoms, some cats infected with the bacteria can develop Feline Bartonellosis disease.
Feline Bartonellosis, caused by the Bartonella bacteria, is in itself not a contagious disease. However, the Bartonella bacteria can be transmitted between cats, dogs, and humans and may lead to some illnesses such as Bartonellosis and a condition in people known as Cat Scratch Fever.
