Feline Mycoplasma

Feline Mycoplasma, (also commonly known as “feline hemotropic mycoplasmas” or “feline hemoplasmas”) is a type of bacterial infection in cats caused by various Mycoplasma species. These organisms were formerly classified as Haemobartonella. The most commonly diagnosed species in cats are Mycoplasma haemofelis, Mycoplasma haemominutum, and Mycoplasma turicensis.



Symptoms can range from mild to severe and may include:

Anemia (pale gums, weakness, rapid breathing)


Jaundice (yellowing of the eyes, gums, and skin)

Weight loss


Enlarged spleen

Poor appetite

It's worth noting that some cats can be carriers of the bacteria without showing any obvious symptoms. So you will not know your feline is a carrier until a very stressful situation occurs, sparking an immune system response. "If you purchase from a breeder and they are genuinely unaware, please do privately reach out to them with the tests as proof. If they remain combative or ignorant please do post the entirety of your whole situation on the Facebook or other platform forums where others discuss dishonest breeders. 


Flea control: Using effective flea preventatives on your cat and keeping the living environment free of fleas is key to minimizing the risk of feline mycoplasma transmission.

Regular vet check-ups: Regularly getting your cat checked by a veterinarian can help detect and treat infections early.

Avoiding fights: Reducing exposure to potential bite wounds, especially in male outdoor cats, can help prevent transmission.

Testing blood donors: If your cat requires a blood transfusion, ensure the blood is sourced from tested and healthy donors.


Antibiotics: The most commonly used antibiotics to treat feline mycoplasma are doxycycline and enrofloxacin. Treatment duration can be several weeks.

Supportive care: Cats with severe anemia may require blood transfusions or additional treatments like fluids, nutritional support, and other medications to alleviate symptoms and support recovery.

Regular monitoring: Even after the completion of treatment, regular vet check-ups are necessary to ensure the infection is cleared and the cat is recovering well.
