Do I have to submit an application without even seeing the cat. There's no way of even knowing if it's available

I think what they are looking for is your interest, they really are happy if you choose one, or come back later and choose one. Once you're approved they feel comfortable adopting to you, so if you choose a Kittie now or within I think 6 months you're good to go. Yeah, they do not want you choosing on looks alone, they want to see you and the Kittie will be happy together

While you do have to list a specific cat to apply, you're not limited to adopting that specific cat! Once you're approved, even if it's for, say, "Miss Kitty," you could decide to adopt "Patches" if you liked them better.

You have to apply to adopt period from them. Then when you go you may be asked the same questions again AND again. Furkids should be called Catnazis...lol
