Many vets will do a complete blood panel, sometimes called a chem-8 or chem-12 or just a blood chemistry that they will run at the same time as the CBC. The blood chemistry will check liver function, kidney function and electrolyte levels. The CBC wil check for anemias, infections, clotting problems...those kind of things.
What was wrong with Reeses back in November? They may just be doing comparisons to make sure there's no on-going problems. You might want to call your vet to see exactly what they're looking for by doing the bloodwork. I just had two cats in last week for CBC and blood chemistry (one for renal failure and one to check borderline renal insufficiency.) It was well
over $300 for both. YIKES!!! Although I feel extremely relieved that they are both stable in the high end of normal range of kidney function, but boy it was tough writing that check!
