my 15 yr old maine coon is suffering from a WBC count of 43k (steadily climbing with each trip back to vet), inappetance, lethargic, not drinking water. he is on baytril, cypro, clavamox. has just come back from vet, having quick/mild sedation for scope down throat, nothing found in mouth/larnyx, tonsils etc. vet is stumped, believes he may have mysterious infection/inflammation or mass due to high WBC. has been given windstrol, B-12 injections, sub q fluids....anyone with any suggestions or experience with this? he is now continually crying softly at midnite after coming from vet just a few hours ago
