Here are the elements I remember about the story (some of which may be wrong). It was about a human (woman I think) who brought home a cat that had been used in biomedical research. The cat was a cat- human chimera, with some human mental capabilities. I think she obtained the cat when it was retired from research. I don't remember what if anything "happened" in the story - I just remember the intense and haunting psychological relationship she developed with the cat. I think the story won an award (I think I read it in a Best SFF of 19xx collection).She also says she read it a few years ago on the web.
It doesn't ring any bells for me. Can any of you readers help?
