cats do not want bath

Remember that the cat is a lot smaller than a human so while the ear itself is large, the inside is pretty tiny. Also you can see the angle. Why is this important? If moisture gets trapped in the ear it’s hard to get out, which can lead to infection. It’s why you see all cats position themselves to avoid getting the inside of their ears wet. Even Turkish Vans (We have several of them) who will sit in the rain are careful to avoid getting water inside their ears.
