Straining in the litter box? Constipation is common in cats. Here's what causes it and how to help.
Recognizing constipation
Signs include straining in the litter box, hard or infrequent stools, small dry pellets, and reduced appetite. A cat repeatedly visiting the box without producing stool needs attention — and shouldn't be confused with a urinary blockage, which is an emergency.

Common causes
Dehydration, low-fiber diet, hairballs, insufficient activity, stress, and litter box aversion all contribute. Older cats and those with kidney disease are especially prone.
Safe relief at home
Encourage hydration with fresh water, a fountain, and wet food. A diet with appropriate fiber and adequate exercise helps keep things moving. Regular grooming reduces hairball-related constipation.
When to see the vet
If constipation lasts more than a day or two, recurs often, or comes with vomiting, lethargy, or pain, see your vet. Chronic constipation needs treatment to prevent serious complications — don't rely on home remedies alone.
