Are pet cats still clean from eating mice?

Generally speaking, owners of pet cats who have eaten rats do not need to worry too much. Cats are natural enemies of rats and are immune to the bacteria on rats, so basically they will not be infected by rats, but they should avoid cats eating poisonous rats. Because rats carry many parasites and disease-causing bacteria, and pet cats will run around at home, when a pet cat is found to have eaten a rat, the owner should first take the cat to a pet shop for a full body wash to remove the germs and worm eggs on the body surface from the rat, and give an external and internal deworming.
