| | + | Cats with colonic impaction may be presented with |
| | + | a history of reduced frequency of defecation or failure to |
| | + | defecate for a period of time ranging from days to |
| | + | weeks. The animal may have been observed to make |
| | + | frequent but unsuccessful attempts to defecate and to |
| | + | spend a prolonged time in the litter box. The cat may |
| | + | also be presented because it is lethargic, inappetent, |
| | + | anorexic and intermittently vomiting. These latter signs |
| | + | may be due to the absorption of bacteria and toxins |
| | + | through the damaged mucosal barrier in the dilated |
| | + | colon. The vomiting reflex is also stimulated by |
| | + | distension of the colon and irritation of the mucosa. The |
| | + | animal may be in a crouched position indicative of |
| | + | abdominal discomfort. |
| | + | Although constipation is usually associated with |
| | + | absence of defecation, the impacted faeces can irritate |
| | + | the mucosa inducing secretion of fluid and mucus that |
| | + | leaks around the colonic mass to give 'paradoxical diarrhoea'. |
| | + | Chronic or persistent straining associated with |
| | + | constipation may lead to perineal hernia or rectal prolapse |
| | + | (Welches and others 1992). |
