Keep working with her to get some nutrition down her.

I was going to ask if you had considered getting another kitten or cat.

I would see if she would adapt to the other one. But I hope you can
at least take some time and go volunteer at your local humane society.

My son used to volunteer before he was hired. And at times they have
200+ cats and kittens. And they are always looking for volunteers for
the cats, its really a big deal when new people come for specifically
the cats, to come and spend time petting and playing with.

So please consider going and volunteering even if its just one day a week
for a little bit of time. Then when you have gotten to know a cat or kitten
maybe you will know which one you want.

PS. Its not giving up on the one you have. Its taking in another. It might
also help the present one. If its lonely.
