I've got me a rescue baby!!

I've been looking all afternoon on the internet at cat rescues hoping to find another edition to my now very small family. I phoned one rescue and they told me about a kitten they've got.
He is just 9 weeks old and was found dumped in a box on some ones door step. He was thin and covered in fleas. He isn't covered in fleas any more and has a healthy appetite and is nice and safe at the centre Also he has had is vaccinations and they don't want a donation fee for him. He also is completely healthy. Not to mention he is cute as a button.
Then the lady asked would I be interested in him? Interested! I'll be over for him tomorow !! Looks like my now quiet home isnt going to be quiet for much longer. Yaaaay !! And this baby ain''t going anywhere !!!

I will also add I havn't given up on searching for my other two Amadeus and Symphony who I "unsensibly" rehomed after listening to much uneeded "unsensible" advice that people thought was actually sensible *sigh*.. anyway Just to let you know I havn't forgotten about thsoe precious two (even though they are safe)!

Is this a reputable rescue organisation?. That's very strange that they don't want a donation for him, and even more strange that their giving him to you so young?.

Is he neutered as well?
