Watching your cat strain in the litter box is worrying. You might see them go in and out, cry out, or produce nothing but small, hard pellets. Constipation is common, especially in older cats, long-haired breeds, and those who don’t drink enough water. The good news is that many cases can be resolved at home with simple changes. This guide walks you through safe, effective steps to get things moving again, and explains exactly when it’s time to call the vet.
1. Increase Water Intake First
The most common cause of feline constipation is dehydration. Cats evolved to get moisture from prey, so many don’t have a strong thirst drive. Start by switching from dry kibble to high-moisture canned food. You can also add a splash of warm water or low-sodium chicken broth to their meals. A cat water fountain often encourages more drinking because moving water triggers their instinct. If your cat is a picky eater, consider using an elevated ceramic cat bowl to reduce whisker fatigue and make mealtime more comfortable, which can help them eat and hydrate better.
2. Add Safe Fiber to Their Diet
Fiber helps bulk up stool and draw water into the colon. The safest and most effective home remedy is plain canned pumpkin (not pumpkin pie filling). Give one teaspoon per meal for an average-sized cat, mixed thoroughly into wet food. You can also try a pinch of psyllium husk powder (like unflavored Metamucil) mixed into food, but start with a tiny amount and ensure your cat drinks extra water. Avoid adding too much fiber at once, as it can cause gas or worsen the blockage. If your cat has chronic hairballs contributing to constipation, switching to a specialized diet can help. Check our guide on the best indoor hairball cat food to find options that reduce hair accumulation in the digestive tract.
A teaspoon of plain canned pumpkin is not a medicine, it is a gentle fiber supplement. It works best when combined with extra water. If your cat refuses it, try mixing it with a small amount of tuna juice (packed in water, not oil).
3. Encourage Movement and Stress Reduction
Exercise stimulates the digestive tract. A sedentary cat is more likely to be constipated. Spend 10 to 15 minutes playing with a wand toy or laser pointer to get your cat moving. If your cat is stressed, that can also shut down their digestion. Stressors include a dirty litter box, a new pet, or changes in routine. Make sure the litter box is scooped daily and placed in a quiet, low-traffic area. For anxious cats, a calming diffuser can make a big difference. You can find options in our guide to the best calming diffuser kits for every budget, which can help relax your cat and support normal bowel function.
4. Try Gentle Abdominal Massage
A gentle belly rub can sometimes stimulate a bowel movement. Wait until your cat is relaxed and lying on their side. Use your fingertips to make small, circular motions on their lower abdomen, moving from the ribcage toward the tail. Apply very light pressure, stop immediately if your cat tenses up or seems uncomfortable. This technique is not for cats with a known blockage or those in obvious pain. It works best as a daily preventive measure for mildly sluggish cats.

5. When to Call the Vet
Home remedies are only safe if your cat is still eating, drinking, and acting relatively normal. You should call your vet if your cat has not produced any stool for more than 48 hours, is vomiting, has a painful or distended belly, is lethargic, or is crying out in the litter box. Never give your cat human laxatives, mineral oil, or enemas without veterinary guidance, as they can be toxic or cause severe dehydration. Your vet may recommend a stool softener like lactulose, or in severe cases, administer an enema or remove impacted stool under sedation.
6. Long-Term Prevention Strategies
Once your cat is regular again, keep them that way. Feed a moisture-rich diet (canned or raw), provide fresh water daily, and keep the litter box clean. Regular grooming reduces the amount of hair they swallow. If your cat is prone to stress-related constipation, maintain a consistent routine and provide enrichment like puzzle feeders and cat scratching barrels and posts for exercise and mental stimulation. A happy, active cat is far less likely to get backed up.
