Overview
Constipation occurs when stool moves too slowly through the colon, becoming hard and dry. In cats, severe chronic constipation can progress to megacolon — a permanently stretched, non-functional colon. Causes include dehydration, low-fiber diets, hairballs, lack of exercise, and certain medications. Senior and indoor cats are most prone.
Symptoms to Watch For
- Straining in the litter box with little or no output
- Small, hard, dry stools
- Decreased appetite
- Vomiting (in severe cases)
- Lethargy and discomfort
How Nutrition Helps
Increased water intake is the most important factor — wet food provides 4-5x more moisture than dry food. Soluble and insoluble fiber help bulk and soften stool. Pumpkin puree is a natural remedy many vets recommend. For cats prone to hairball-related constipation, hairball formula foods with added fiber help.
How Activity Helps
Regular exercise stimulates intestinal motility and helps move stool through the colon. For indoor cats, daily interactive play sessions are essential. Even 15 minutes of active play can improve gut function.
Prevention Tips
- Feed wet food or add water to dry food
- Provide multiple fresh water sources
- Add pumpkin puree (1-2 tsp) to meals
- Ensure daily exercise and play
- Groom regularly to reduce hairball ingestion (cats)
Breeds at Higher Risk
Older indoor cats, Persian and Siamese cats (hairball-prone), English Bulldogs, and Basset Hounds.
