TICKS
Cats can contract several diseases from ticks, although these infections are generally less common in cats than in dogs. Here are some of the key tick-borne diseases that can affect cats:
1. Cytauxzoonosis
- Cause: This disease is caused by the protozoan parasite Cytauxzoon felis.
- Transmission: It is transmitted by ticks, particularly the Lone Star tick (Amblyomma americanum).
- Symptoms: Symptoms include fever, lethargy, loss of appetite, jaundice, difficulty breathing, and sometimes sudden death. The disease progresses rapidly and is often fatal if not treated promptly.
2. Anaplasmosis
- Cause: Anaplasmosis is caused by the bacteria Anaplasma phagocytophilum.
- Transmission: This bacteria is transmitted primarily by the black-legged tick (Ixodes scapularis), which is also known as the deer tick.
- Symptoms: Symptoms in cats may include fever, lethargy, joint pain, loss of appetite, and anemia. Although more common in dogs, cats can still be affected.
3. Ehrlichiosis
- Cause: Ehrlichiosis is caused by bacteria from the genus Ehrlichia, with Ehrlichia canis being a common species.
- Transmission: Ticks, particularly the brown dog tick (Rhipicephalus sanguineus), are the primary vectors.
- Symptoms: Infected cats may show signs such as fever, lethargy, weight loss, swollen lymph nodes, and anemia. While rare in cats, it can lead to chronic infections if not treated.
4. Lyme Disease (Borreliosis)
- Cause: Lyme disease is caused by the bacterium Borrelia burgdorferi.
- Transmission: The disease is transmitted by the black-legged tick (Ixodes scapularis).
- Symptoms: Cats may experience fever, lethargy, lameness, joint pain, and loss of appetite. Lyme disease is more commonly recognized in dogs and humans, but cats can be infected as well.
5. Tularemia
- Cause: Tularemia is caused by the bacterium Francisella tularensis.
- Transmission: It can be transmitted by several tick species, including the dog tick (Dermacentor variabilis) and the Lone Star tick (Amblyomma americanum).
- Symptoms: Symptoms in cats include fever, lethargy, loss of appetite, swollen lymph nodes, and abscesses. Tularemia can be severe and is a zoonotic disease, meaning it can also infect humans.
6. Babesiosis
- Cause: Babesiosis is caused by protozoan parasites of the genus Babesia.
- Transmission: Transmitted by various tick species, though it's more commonly reported in dogs, cats can still be infected.
- Symptoms: Cats may show signs of fever, anemia, lethargy, and jaundice. Babesiosis is rare in cats but can occur.
7. Hepatozoonosis
- Cause: Hepatozoonosis is caused by protozoan parasites from the genus Hepatozoon.
- Transmission: Cats typically acquire the infection by ingesting an infected tick rather than through a bite.
- Symptoms: Symptoms include fever, muscle pain, weight loss, and lethargy. Hepatozoonosis is uncommon in cats.
These diseases highlight the importance of regular tick prevention and monitoring for symptoms in cats, especially in areas where ticks are prevalent.
FLEAS
Cats can contract several diseases from fleas, some of which can be serious or even life-threatening. Here are the key flea-associated diseases that can affect cats:
1. Flea Allergy Dermatitis (FAD)
- Cause: Flea Allergy Dermatitis is an allergic reaction to flea saliva.
- Symptoms: Cats with FAD experience intense itching, skin inflammation, hair loss, scabbing, and secondary skin infections due to excessive scratching and grooming. Even a few flea bites can trigger this condition in sensitive cats.
2. Bartonellosis (Cat Scratch Disease)
- Cause: This bacterial infection is caused by Bartonella henselae and is transmitted by fleas.
- Symptoms: Infected cats may show mild to no symptoms, but when symptoms do occur, they can include fever, lethargy, swollen lymph nodes, and inflammation of the gums, eyes, or heart. Cats can also transmit this disease to humans through scratches or bites, where it may cause swollen lymph nodes, fever, and other symptoms.
3. Hemoplasmosis (Feline Hemotropic Mycoplasmosis)
- Cause: This disease is caused by blood-borne bacteria known as Mycoplasma haemofelis and related species, transmitted by flea bites.
- Symptoms: Cats with hemoplasmosis may develop anemia, fever, weakness, loss of appetite, and jaundice. The disease can be severe, especially in immunocompromised cats or those with other underlying health conditions.
4. Tapeworms (Dipylidium caninum)
- Cause: Tapeworm infection occurs when a cat ingests a flea that is carrying the tapeworm larvae.
- Symptoms: Infected cats may show signs of weight loss, vomiting, or see small segments of the tapeworm (resembling grains of rice) around the anus or in the feces. While not usually severe, tapeworms can cause discomfort and gastrointestinal upset.
5. Flea-Borne Rickettsiosis
- Cause: Caused by Rickettsia felis, a type of bacteria transmitted by fleas.
- Symptoms: Infected cats might show non-specific symptoms such as fever, lethargy, and loss of appetite. Though more commonly recognized in humans, rickettsiosis can affect cats as well.
6. Plague (Yersinia pestis)
- Cause: While rare, fleas can transmit the bacterium Yersinia pestis, which causes the plague.
- Symptoms: Cats with plague may exhibit fever, swollen lymph nodes, respiratory distress, and lethargy. This disease is very serious and can be fatal if not treated promptly. It's also zoonotic, meaning it can be transmitted to humans.
7. Flea-Borne Typhus
- Cause: Flea-borne typhus is caused by Rickettsia typhi, transmitted by fleas.
- Symptoms: Symptoms in cats are generally mild but can include fever, lethargy, and loss of appetite. The disease is more commonly recognized in humans, particularly in regions where flea infestations are prevalent.
8. Feline Infectious Anemia
- Cause: Feline infectious anemia is primarily associated with Mycoplasma haemofelis and similar organisms, which are transmitted by fleas.
- Symptoms: Anemia, lethargy, weakness, and jaundice are common signs. Severe cases can lead to life-threatening conditions if not treated.
These diseases highlight the importance of flea prevention and control in cats. Regular use of veterinary-approved flea preventatives can help protect cats from these flea-associated diseases.
