===Clinical Signs===
Cats with megacolon typically present with a history
of chronic constipation, tenesmus, anorexia, vomiting
and weight loss. Perineal swelling is seen in those with
concurrent perineal herniation. Any animal that presents
with megacolon should be subjected to a full clinical
examination and diagnostic evaluation to rule out concurrent
diseases such as perineal hernia, rectal stricture,
pelvic fracture malunions or colorectal neoplasia. A
complete neurological examination and routine laboratory
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.
