Abstract: In this paper, the red blood cell（RBC）, hemoglobin （HGB）, hematocrit（HCT）, mean corpuscular volume （MCV）, mean corpuscular hemoglobin（MCH）, mean corpuscular hemoglobin concentration （MCHC）, red blood cell distribution width （RDW-S）and red blood cell distribution width coefficient of variation（RDW-C）of 1 203 clinical cases were analyzed statistically. The results showed that:（1）18.95% clinical cases had dehydration, and 9.64% clinical cases had anemia, including 61.74% mild anemia cases, 24.35% moderate anemia cases, 11.30% severe anemia cases, and 2.61% extremely severe anemia cases.（2）The ranges of RBC, HCT, MCV, MCH, MCHC, RDW-S and RDW-C in the 859 clinical cats with normal HGB were （2.27-13.84）×10¹²/L, 11.60%-59.00%, 26.90-94.60 fL, 9.30-29.70 pg, 240.00-576.00 g/L, 23.00-54.54 fL and 12.50%-37.10% respectively.（3）In 116 clinical cases with anemia, the macrocytic, normal, simple microcytic and microcytic hypochromic anemia cases accounted for 26.72%, 56.90%, 14.66% and 1.72% respectively; Macrocytic, normal and microcytic homogeneous anemia cases accounted for 9.48%, 16.38% and 3.45% respectively; and non homogeneous anaemia cases accounted for 17.24%, 40.52% and 12.93% respectively.
