can changing her diet help?

reducing the Iron intake in food helps lower red blood count, I don't know if it work on cats though.

I don't think that will change anything due to the fact that her red blood cell count isn't just a little high.  It's very high, to the point of making her blood visibly thicker.  The fact that her iron levels are normal, I don't really think it is an issue.  She generally has a balanced diet.  It seems like she still has problems, unfortunately.  Now she's having different symptoms that make me wonder about the whole thing.  She will be having a visit to a vet clinic with more advanced tools on Friday.
