I suggest that you request 3-5 descriptive words about each kitten/puppy that are not 'fuzzy, fun, active, etc'... More specific to the individual animal than 'general'. And to ask the foster what type of family/person would this animal thrive with or could they imagine this animal living with... We had one kitten last year that was:
'a great shoulder rider and climbed up to get there! She would have been great company to someone who traveled for work or pleasure or for a trucker!'
While a kitten climbing your legs is NOT my idea of a great thing, we absolutely couldn't seem to break her of it - so we just learned to work with it. She actually goes to work with her new Dad now - every day! He drove 5 hours to see her when she was almost ready for adoption & then came back when she was ready (after her surgery) to take her home... He also harness & leash trainer her & it has been a great match for both of them - she is his constant companion, gets lots of activity & visits well with others & then settles down at night with him, sleeping through the night.
I guess my point is when you get good descriptive info from the foster, it is easier to write a bio... I have found that in some cases it is hard not to repeat info, though. I mostly bottle feed which means our kittens are:
'more like 'little dogs' than cats & they almost never have 'cattitude' like a regular cat. They will meet you at the door & are constantly following you around, coming when you call their name (etc, etc) & will always want to lay on you - in your lap, on your chest or next to you in the bed. They don't know to protect themselves like other cats so you have to be prepared to keep them indoors only or provide a very safe and protected area for them if they will be an indoor/outdoor cat. They have been exposed to adults, children & adult cats, but will do well with other cat-friendly animals'.
Believe it or not I have had folks call who didn't want a cat that was a lap cat - but that's what bottle babies become... The more you know, the better you can serve the public & the animal!
Another thought - I know people re-name their animals & I think that's fine, but I try to make sure that all my babies know their names & are 'treat' trained - in other words, they come when I call 'TREAT'... This is a good thing for new animal owners because a new home can sometimes be overwhelming to a kitten/cat & if you call 'TREAT' they will (eventually) come for it (usually)... It has worked for a few 'new' homes that we placed our kittens in... It also helps if your foster 'parents' (or a foster) are open to talking with folks AFTER the adoption - new parents sometimes text me at 10pm wanting to know 'is this okay?' or should I take her/him to the emergency vet? is this 'normal'? When they have someone to ask it can sometimes help them feel much more comfortable & I think it helps with animal retention...
