Used with an adult cat. Based on other reviews I should note there are two main reasons for a cone. To keep an animal from scratching their head, OR to keep an animal from biting or licking their body. This is only good for the second scenario, which is what I needed it for. The cat does not like it as much as the clear plastic cones, but any of those big enough to keep him from licking his sores also prevent him from eating and drinking. This keeps him from reaching his incision (rear leg amputated) with his mouth, but he can still get to food because it is cloth. It does seem to make him feel more trapped and bummed out, but out of the three I ordered, it is the only one that covered the medical need.
Will keep them from biting their body, not from scratching their head.
