Ragdoll Cat

　　1. Feline Toxoplasmosis

　　Pathogen: This disease is caused by the intracellular parasite Toxoplasma gondii residing in cats and is a zoonotic protozoan infection.

　　Symptoms: When cats are intermediate hosts, symptoms are divided into acute and chronic types.

　　Acute type: Infected cats have fever, often with body temperature above 40℃. They show lethargy, anorexia, drowsiness, and difficulty breathing. Sometimes vomiting and diarrhea occur. Pregnant cats may experience stillbirth and abortion.

　　Chronic type: Loss of appetite, emaciation, and anemia; occasionally neurological symptoms appear. Pregnant cats may also have miscarriages and stillbirths. When cats act as the definitive host, symptoms are milder, usually presenting as mild diarrhea.

　　Prevention and treatment: ① Maintain cleanliness of cat houses, promptly dispose of cat feces, regularly disinfect, and strictly disinfect aborted fetuses, excretions, and abortion sites to prevent environmental contamination.

　　② Medication treatment can use sulfadiazine at 10mg/kg body weight, orally divided into 4 doses daily; or pyrimethamine at 1mg/kg body weight once daily for 7 consecutive days.

　　This disease can infect humans; personal protection is important.
