Inflammation of the cat's anal glands cannot heal on its own. The owner needs to help the cat clean the anus regularly with saline or hydrogen peroxide. If there is already pus, it is best to go to the hospital to squeeze it out, and then apply anti-inflammatory ointment. It is usually best not to let the cat lick the wound, otherwise it will easily become infected. You can choose tofu sand or crystal litter for cat litter, which is cleaner. In terms of diet, try to be as light as possible, and do not feed difficult-to-digest foods to avoid causing constipation and aggravating anal gland inflammation.
