The right home for the right cat?

I got an application on one of my cats today from a family that seems great but they are not quite what I had in mind for the cat that they are interested in. They seem like good, loving, responsible people but the issue is that they don't have any other cats and they have a dog, although a cat friendly dog.
The cat, Lucky, is a very sweet and pretty boy but he is a rehabilitated feral and he still has some issues with shyness. Since he spent his first 5-6 months of life with other cats only he is still very comfortable around other cats. He may do just fine as an only cat but I fear that he may not and would be too uncomfortable and skittish. I have two dogs so he is used to living with dogs but unfortunately he has some issues with one of them. One of my dogs is great with the cats and Lucky is fine with him but my other dog has issues with cats that act fearful around her, especially if they hiss at her. She will take after them and chase them out of the room. Lucky is afraid of her so of course he hisses at her whenever he sees her which causes her to try to chase and Lucky gets even more scared.
Since the dog that the adopters have have lived with other cats and is good with cats Lucky may do just fine with him but he also may not.

Good homes for adult cats do not grow on trees so I'm reluctant to turn one down and chances are that Lucky would adjust just fine and be happy there. But they are not what I had in mind for him and I fear that he would not do well there. However, cats are adjustable and in time most learn to live and do well in their environment. Almost every foster I've had have adjusted even though they've had a hard time in the beginning. Every cat can't find a perfect, ideal home so I shouldn't be too picky.

What do you guys think? Should I take a chance on this home for Lucky or should I suggest another cat for the family and wait until a more ideal home comes along for Lucky? I would hate to turn down a home where he could have a great life but then again I don't want to risk putting him through a situation where he's scared and unhappy.

It's hard to know, if Lucky is going to very shy & need a lot of time to adjust - then it makes it hard for them to know how he'll do with the dog.

Do you think they would consider adopting another "well-adjusted" cat along with Lucky to help him settle in? Do you have such a thing, and do you think this is a good idea?

If they sound reasonable enough, honestly, I've found that you can just talk to adopters about concerns. If you don't like the response you get from them - tell them no you can't have him. If you do like the response you get, it may be worth a gamble to see how he does. (Obviously if it doesn't work out - it's hard on Lucky to make the adjustment & then end up coming back to you)

Billy is a former feral we kept because we were unable to adopt him out with his brother. The family that adopted his brother (Bing) sounds like you just described - a cat friendly dog (they had two young boys). Mom wanted to take both cats - DH said just one. We'd been working on finding them a home for months - and Winter was upon us and we can't foster cats inside. We were VERY worried that Bing would be lonely, and we had no idea how he'd do with dogs. It tore our hearts apart, but we could not keep them both and we could not leave them outside another winter - and they were VERY close.

Billy cried for months missing his brother even though we already had six cats (they co-exist but aren't bonded to each other or anything).

Bing (the one adopted out) was shy - but the family was prepared. He came out of his shell by playing "attack the dog," it took him over a month to venture downstairs from upstairs - and then he'd do it only at night. He ended up bonding closely to their youngest child. We got updates via e-mail every few weeks at first then every few months. It was about one year after his adoption that we got the update that Bing is "king" of the house, shy around strangers, but otherwise has claimed the entire home as his, totally playful (having learned what toys are), happy, loved, and gets a lot of attention from his people (especially "his" little boy). To solve the "attack the dog" problem, they bought cat trees and put up a lot of vertical space for him - that seemed to help. (It made him visible to the dog, who could then avoid him. Otherwise he'd hide behind things and leap out and attack the dog).

I would encourage them to take two cats - I think Bing would have been happier sooner with another definitely cat-friendly cat. But it did work out adopting him out as an alone cat - it just took time and patience, and thankfully, they were the right family from that perspective.

Five of our six accepted Billy without too much trouble, and Shelly and Tuxedo groom him for short bursts when he asks for it (at least daily LOL). Flowerbelle and Ming Loy play with him. But they all think he's an alien, constantly trying to headbutt them (he's an eternal optimist - he's been inside with us 1 1/2 years now, and he still tries ).
