How should the free-range cat adapt to the situation when he is suddenly not allowed to go out?

In fact, whether the cat is dirty or not depends entirely on the living environment. If the cat is allowed to come in and out freely and is kept free-range like in the countryside, it will not be too clean. But if the cat lives in a building and the house is cleaned frequently, then Cats are not too dirty. After all, cats are relatively clean compared to other animals. They chew and spend a lot of time taking care of themselves every day. Moreover, the hair of domestic garden cats is relatively short and easier to take care of. If it is a long-haired cat, it may not be able to clean it by itself and needs help from someone to comb it. It is best not to bathe a cat that has just been brought home. It is not too late to wash it after it has adapted to the new environment. If it is clean and extremely dirty, you can just wipe it with a wet towel first. About a week after arriving home, if there are no abnormalities, you can prepare for deworming and vaccinations. Deworming medicine can be bought at a pet hospital or online. Internal deworming is to take medicine, and external deworming is usually drops, which should be dropped on the skin on the back of the neck so that it cannot lick it by itself.
