Once your cat is comfortable and settled in your lap, grasp the ear, and straighten the canal to expose some of the creases that might be hidden.
Grab your bottle of ear cleaner in the opposite hand and squirt it into the ear canal. You should try to fill the whole canal but don’t worry if some leaks out. Try to avoid any contact between the nozzle of the bottle and the ear, it doesn’t need to be inserted into the ear, just squirted down the ear.
Still holding their ear, you can put down the bottle and use that hand to now massage the base of the ear for thirty seconds to a minute to give the solution time to break down any wax that’s stuck against the ear. While massaging you should hear the solution moving around in their ear.
Taking a cotton wool pad or ball, use it to remove any softened wax and debris from the ear, starting at the deepest point and wiping outward towards the tip of the ear. The solution should make the wax nice and soft so it’s easy to remove.
