Diseases that cats can infect humans:

1. Rabies, caused by rabies virus, is the second source of infection after dogs. Cats infected with the virus can excrete it through their saliva, and humans can become infected if they are scratched or bitten by cats. Rabies is one of the most serious malignant infectious diseases to date. Once infected, the fatality rate is 100%. Therefore, you must be vaccinated against rabies in time after being bitten by a cat.
2. Toxoplasmosis. Toxoplasma gondii is an opportunistic parasite. Cat feces contain its oocysts, which can infect the human body if ingested. Toxoplasma gondii is an opportunistic pathogenic parasite. Most people with normal immune function are infected with latent infection without any symptoms or signs. About 10%-20% of patients have clinical manifestations, showing mild cold-like symptoms. Patients will have lymph node swelling and pain, but no suppuration, and cervical and axillary lymph nodes and rectum are involved.
3. Cat-scratch disease, caused by infection with Bartonella henselae, occurs after being scratched or bitten by a cat.
4. Cat ringworm, caused by spores, is transmitted to humans through close contact.

Causes for cats to suffer from catnip:

1. The environment is unclean and contains a lot of fungi.

2. The environment is warm and humid, and fungi can easily breed.

3. Direct contact with other animals or objects carrying pathogens.

4. Indirect contact with pathogens, the transmission medium can be people and objects.

5. Cats with low immunity caused by being too young or too old. For example, milk cats are more likely to get catnip.

6. Cats have low immunity caused by stress.

7. Cats have low immunity caused by nutritional deficiencies.

8. Cats lack nutrients, such as essential fatty acids and vitamins, resulting in low skin resistance.

9. Feline AIDS, an immunodeficiency disease in cats, research shows that this will make cats three times more likely to be infected with catnip than healthy cats.

10. Wounds caused by cat fights can also easily become the origin of cat moss.
