Also commonly performed are the opening and draining of abscesses, often caused by bite wounds but sometime involving the tooth sockets are mammary glands, cleaning and extracting teeth, suturing wounds and arresting severe hemorrhage, and removing tumours from the skin, mammary glands and mouth. Foreign bodies may have to be surgically removed from the skin, tongue and pharynx and sometimes from internal organs such as the stomach or intestines.

Male cats suffering from feline urological syndrome, causing blockage of the urethra, need to be catheterized to withdraw the urine which cannot be passed, or if this proves difficult, to have urine removed via a needle interested through the abdominal wall. At times males that repeatedly suffer from this condition may have the points removed, thereby eliminating the site of the obstruction, and a new opening is created for the cat to pass urine (perineal urethrostomy).
