Hi Vanessa, I think the honest answer to your question is that it depends on the rescue.
I started fostering for a small independent rescue last year, and whilst I'm very much aware (as are the other volunteers) that life in a pen is far from the ideal, I know everybody tries to make life as bearable as possible for each cat taken on. There is no main cattery as such, so all pens are in volunteer's back gardens, and I know of several 'long stay' cats, mainly older or feral, that have been given the run of the garden in the daytime so as to give them some semblance of a life, or at least moved to a pen with an outdoor run, until a more permanent solution can be found. No cat is ever put down unless it's for health reasons and the kindest thing, when any loving owner would make the same decision. I have two permanent foster cats living with my own gang that are older and have on-going health problems, and there are several other permanent foster cats living in homes, considered 'unhomeable' but still under the care of the rescue. I'm sure we'd all love smarter, bigger pens and better food, but we do the best we can and rehome a good few cats - I'm sure there are many small rescues out there that operate in much the same fashion. It might be worth finding out a bit more about the rescues in your area?
I had to make the same decision that you are facing last year, when a stray I had fostered and fallen for started to bully the rest of my cats and I had to remove him for the sake of my own gang. It felt rotten having to move him to a small pen under another's care, but within about a week he was spotted and is now in the absolute perfect home for him, with a doting cat slave who adores him (and sends me updates). Even if he'd been in a pen for a couple of months I think, on balance, it would have been worth it. Hopefully, he now has a lifetime ahead of him that will be lived as it should have been from the start.
What I did learn is that people tend to want to meet the cats, and are more likely to visit a cattery where they can view several at the same time. If the cat is friendly and approachable, basically will 'sell itself', it's much more likely to be homed quickly in a cattery. I've taken another cat over to our biggest 'cattery' (12 pens) since, and after a couple of months with me (I have one outdoor pen and a spare room) and no interest, she too went to her new home within about a week. For shy or feral cats, I'm not so sure ...... it's a difficult one.
I have no doubt that the cats are well cared for with you, and bless you for taking such good care of them. Please forgive my rambling, I hope that helps!
ADDED: I'm glad you managed to get him sorted out! Give him a fuss from me, he's lovely.
