I hope you understand that I'm not saying this to criticize you, only trying to speak as the voice of experience - but bonding with a cat's picture and story is very different from bonding with a cat face to face. All cats have quirks and different ways of being demanding that can really take you by surprise and throw you for a loop. That pretty face can conceal serious behavioural problems; on the flip side, the plainest cat in the shelter may be the most loving pet you could ever want. There's no way to be sure you will click with a particular cat aside from spending time with him or her.
I don't think anyone is suggesting that you settle for a cat you feel no bond with or have no interest in caring for; that wouldn't be a good thing for either you or

I would also strongly caution you against thinking of any cat as yours before the paperwork is signed and you bring them home. You can set yourself up for tremendous heartache that way. Even if the cat is available, you may not be chosen, or the rescue organization may decide that your home doesn't have the resources to support the cat's special needs, or the foster home may decide to keep the cat as a permanent family member, or in rare cases the cat may even become unadoptable or die before you can bring him or her home.
I know feeling a bond can happen easily and isn't always preventable even if you wanted to. (There's a cat I saw at an adoption event a few months ago that I still think about, but for various reasons me not adopting her was the right decision for all involved, including the cat herself.) I also think you have to be a bit realistic, though, that a cat isn't yours until the cat is
I wish you well in finding your new pet.
