An update on hematologic, biochemical and urinary reference values for Iriomote cats.

Area of Science:

• Veterinary Medicine
• Wildlife Conservation Biology
• Zoology

Background:

• The Iriomote cat (Prionailurus bengalensis iriomotensis) is a critically endangered wild felid subspecies.
• Limited hematological and biochemical data exist for Iriomote cats, hindering health assessments.
• Establishing reference ranges is vital for monitoring the health of endangered species.

Purpose of the Study:

• To evaluate hematology, serum biochemistry, and urinalysis values in Iriomote cats.
• To identify sex-specific differences in these health indicators.
• To compare Iriomote cat values against a reference range established for domestic cats (Felis catus).

Main Methods:

• Hematology and serum biochemistry analyses were performed on 69 Iriomote cats.
• Urinalysis was conducted on 56 Iriomote cats.
• Statistical analyses were used to determine sex differences and compare values to domestic cat reference ranges.

Main Results:

• Significant sex differences were observed: males had higher red blood cell counts and total cholesterol, while females had higher platelet counts.
• Iriomote cats exhibited values above the domestic cat reference range for aspartate aminotransferase, glucose, blood urea nitrogen, creatinine phosphokinase, and lactate dehydrogenase.
• Urinalysis indicated the presence of white blood cells and marginal protein levels, likely associated with stress and activity.

Conclusions:

• This study provides essential hematological and biochemical reference data for the Iriomote cat subspecies.
• The findings highlight potential health indicators and sex-specific variations in this endangered felid.
• Understanding these health parameters is crucial for conservation efforts and veterinary care of Iriomote cats.
