Haematology and biochemistry may give evidence of dehydration, such as raised packed cell volume, total protein and urea/creatinine. A stress leukogram may also be seen. The duration of constipation may result in changes to blood electrolytes, and dehydration can lead to pre-renal azotaemia. Urinalysis should always be perfored to rule out lower urinary tract disease as a differential diagnosis and to check renal function in dehydrated animals.

evaluation (haematology and biochemistry, serum

electrolytes and urinalysis) should be carried out.

Thyroid function should be checked in younger cats,

as obstipation can be seen with juvenile-onset hypothyroidism.
