"Non-regenerative" as a class suggests that the bone marrow is not specifically involved. Suggests, not states. So the test *may* be useful, not *will* be useful.

7 is young for a cat, given that they will often make 20 these days with good vetting.

The best Vet School in the state is Penn Vet - be prepared to max out any of several credit cards if that is your choice - but they do know what they are doing, they are incredibly well-equipped and they are on the bleeding edge of cutting edge in their treatments.

That she is showing some pinkness is a hopeful sign, and that she is cancer-free (other than the Anemia) is also hopeful. Now, one more thing - if she is sneezing a great deal, have her tested for feline herpes. Our big guy (11-year old 20 pound Maine Coon) was diagnosed when he was 4 months old. He was treated with Lysine for a full six months, which forced it into remission. He has been symptom free since. But when it was active, he had all sorts of complications including projectile vomiting, sneezing, lethargy, extreme weight loss and similar issues. For all that, his eyes were never involved, so that was not the first thing the vet thought of - until he started sneezing. Whereupon he went right there.

Best of luck.
