Hello!
So we send out singletons to foster all the time as we do not want to mix litters for health reasons. I also have fosters who do not have another other animals in their home so are raised as the only kittens. The biggest thing is socialization and exposure to a lot of different sights, sounds and stimuli. We also don't recommend our foster kittens interacting with adult animals until after 14 days incase they have any underlying diseases.
We also do not limit any adoptions based on if they want to adopt a single kitten. A lot of times we will explain that this kitten is a singleton so may take time to learn being around other animals or have other quirks from being raised by itself.
I have had kittens in litters that behave worse then singleton kittens so it really depends on their personality and their exposure in the foster home. We don't always know the path they are going to go on so as long as the adopters are willing to work with them that is the most important thing.
