Calling her a goddess may or may not be accurate. A netjer/ntr/neter yes, but a goddess maybe not. The reason why is that oftentimes in ancient Egyptian cultural/spiritual practices, there isn't much difference between a netjer (a deity) and a netjeri (a non-human spirit). The term netjer/ntr/neter has been hypothesied to be connected to the term nature (to describe a spirit of nature or of a natural thing), while netjeri were given lesser jobs, such as of servants of the netjer (servants/fairies of a spirit of nature). Calling them fairies isn't entirely accurate, as fairies is a different culture's term, and also some of them aren't servants of a spirit of nature, but the group of them that I'm talking about is and could be compared to fairies.
So there is a Bast, there is a Bast-Mut, a Sekhmet-Bast-Ra, and there are Bast netjeri (who are a spirit of Bast/representative of Bast), etc. Just because the Bast you work with might be described as a goddess, doesn't mean every Bast is a goddess.
At least, that's all in relation to ancient Egypt and the Kemetic Orthodoxy. I'm sure a general recon slant will be different. :)
