This is a white AG cat that was available from AG around the turn of the century. She originally came with two little clear vinyl backpacks filled with nail polish and manicure accessories and was called the "Hand Care Kitty" or something similar.
I think she was originally about $25 new from AG. I got mine from an estate sale for $9 because I was excited with the rareness of the thing, though she didn't have her original backpacks or accessories.
Here she is next to Angelina for a size comparison:
She's really floppy and fun to play with:
She has an "American Girl made in China RN 92138" white tag on the back of her left leg.
