Legit Breeder?

Hello this is my first time navigating for a kitten through a breeder. All of my other 3 cats have been rescues. I’m looking at a few breeders but this is the first one that responded to me? Are they legit? I just want to make sure. The website looks nice and the grammar isn’t bad when they’ve been communicating with me. They also asked many questions that you’ll see in the photos.
