Constipation, often suspected by pet owners (but in fact it rarely occurs in pets,) occurs when the pet is unable to properly evacuate its bowels. As a result, the feces remain in the colon where water from the fecal material continues to be absorbed by the colon. The fecal matter dries out and forms a hard mass. While constipation can occur in dogs (usually as a result of eating large amounts of foreign material,) true constipation occurs more often in cats (although it is quite rare in cats as well.) Cats can develop an unusual form of constipation or obstipation (severe constipation) called megacolon.

In this disorder of unknown cause, the colon loses its ability to effectively contract and cause voiding of feces. Cats and dogs suspected of having constipation should be evaluated immediately, as blockage of the urinary tract (which can be fatal) is often mistaken by the owner as constipation (which is unlikely to be fatal.)
