How to feed Birman and Siamese cats:

1. Deworming and immunization. Make sure to regularly inject Birman and Siamese cats with rabies and other vaccines. When bitten or scratched by a cat, you should go to the hospital for treatment in time. Cats should be dewormed regularly. If the cat is not used for breeding, it is best to castrate the cat.

2. Feed with caution. When raising Birman cats and Siamese cats at home, you should also pay attention to keeping the food eaten by humans as much as possible and not letting cats chew it. Once you find food that has been chewed by your cat, it is best to throw it away and not eat it again. When feeding animal livers to cats, it is best not to exceed 1-2 times a week. Otherwise, cats may easily get sick if they eat too much. During the growth and development period of cats, as well as during the period of pregnancy and lactation of kittens, some raw meat, raw liver, and milk can be appropriately fed to prevent cats from suffering from vitamin deficiency. If your cat is found to have oral ulcers, weight loss, etc., you can also feed it some raw meat or raw animal liver.
