A 3-year-old neutered male domestic shorthair cat was referred for subtotal colectomy because of chronic constipation; the cat had had constipation since it was 6 weeks old. The cat had been treated with cisapride (1 mg, PO, q 12 h), lactulose (1 mL, PO, q 8 h), and canned pumpkin (amount and frequency not known) for 6 months prior to evaluation with no response. The decision to refer was based on an increase in the cat’s requirement of enemas (20 mL/kg [9 mL/lb] of tap water and petrolatum) from every 3 to 4 months to weekly.
