My research tells me that the iPad screen could be scratched by a cat. It is almost impossible to find solid information on the subject. It is relevant because there are lots of apps for the iPad that have been created to amuse cats. They all result in the cat jabbing and pawing at the iPad screen but does the cat leave a scratch? You might have a cast iron answer.
It is not even clear that the iPad glass is gorilla glass. I am not sure it is and even if it was that does not guarantee that a cat can’t scratch it. My research tells me that the type of glass is a secret. If an iPad screen is real glass, or as hard as real glass, it won’t scratch because a cat’s claws are made of keratin which is softer than glass.
If I apply some common sense, I have to decided that the glass can be scratched. It must be tough and very scratch resistant but it can be scratched.
So, returning to the question: can a cat’s claws scratch the screen when playing a game on the iPad? Yes, possibly but I am guessing when I say that in normal use by a cat the screen won’t be scratched. I don’t even think one of those “geniuses” on the Apple Store genius bar could answer the question with certainty.
The video shows a cat with what seems like claws playing on an iPad. You can hear the clatter of the claws against the glass. The owner said there were no scratches afterward.
There are protectors for all kinds of screens. They would prevent the screen being scratched but a lot of people don’t like them as they spoil the product.
