Thank you for all the info everyone! So it seems confirmed that she is a Himalayan.

If I remember correctly Himalayans are a mix of Siamese *c(h)* and albino (PEW) *c*, so my rat is most likely *aacc(h)*, So if I wanted to produce a Siamese (which I certainly do) I would have to bred her either a Siamese or another Himi, right?
