Holly is quite the little beauty

. How wonderful that you're considering adopting her should you be able and willing in the future -- taking on special needs kitties is such a rewarding and humbling experience.
I've had just one kitty with FIV (though I've fostered and even was owned by other special needs cats). Her name was Layla and she was a beautiful long-haired brown tabby. We had her while growing up and I knew nothing about FIV then. But, I did know that she was "sick" and could possibly never live a full, long life. However, that most certainly was not the case. Layla lived to be 19 years old and had very few health issues despite having FIV. Unfortunately, she did require some vet care and my parents were unwilling to properly care for them -- thus, I took her and gave her to the sister of one of my closest friends. I told my family that she had run off, but, really, I knew she was safe in the arms (and lap!) of an owner who adored her. My friend's sister loved Layla and took excellent care of her. I wish I could have kept her myself, but at only 10 years old, there's not much I could've done. And, in the end, Layla was in the right home with the right owner. And, the sister who adopted Layla? She now only adopts FIV+ kitties

.
I hope you're able to adopt Holly. She looks like she's already staked her claim on you
