Constipation in Dogs and Cats: Safe Home Care

Constipation is common, usually manageable at home, and occasionally a symptom of something that needs surgery. It also has one dangerous impostor that owners misread every single day.

That impostor is the reason this page exists at all, rather than a short paragraph about fibre and water. Everything else here is the easy part.

Rule out the emergency first

A male cat straining in the litter tray and producing little or nothing is a urinary blockage until proven otherwise.

It looks exactly like constipation: the cat goes to the tray repeatedly, crouches, strains, and nothing comes out. The difference is that a blocked bladder kills within about 24 to 48 hours.

Signs pointing to urinary rather than bowel: crying while straining, repeated visits producing nothing, licking at the genitals, a tense painful abdomen, vomiting, and rapid deterioration.

If there is any doubt at all, treat it as urinary and go now. Being wrong about this in the other direction costs a cat its life.

What constipation actually looks like

• Straining, with little or no stool passed
• Hard, dry, small stools, sometimes with a mucus or blood coating
• Fewer than usual bowel movements over days
• Crying or obvious discomfort while trying
• Reduced appetite, lethargy
• Occasional vomiting in longer cases
• Small amounts of liquid stool passing around a hard mass, which owners frequently mistake for diarrhoea

Common causes

• Dehydration, the single most common, particularly in cats on dry food
• Insufficient dietary fibre
• Hair, in long-haired and over-grooming cats
• Swallowed material: bone fragments, fabric, sand, litter
• Pain, from arthritis, anal glands or a previous injury, making the posture uncomfortable enough to avoid
• Litter tray problems. A dirty tray, a tray in a busy place, or bullying by another cat causes retention
• Reduced activity, especially in older animals
• Enlarged prostate in unneutered male dogs
• Obstruction from a foreign body, a mass or a pelvic injury that has narrowed the canal

Safe home care

Appropriate only for a mild case in an otherwise bright animal that is eating and has been constipated for a short time.

• Increase water intake. Wet food, water added to food, extra bowls, a fountain for cats
• Add fibre, such as a small amount of plain cooked pumpkin, on veterinary advice for amount
• Gentle exercise, which stimulates gut movement
• For cats: clean the tray more often, add another tray, move it somewhere quieter
• Groom more, if hair is contributing

Give it a day or two. No improvement means a vet.

What never to do

• No human laxatives. Several are dangerous, and some cause severe electrolyte disturbance in animals
• No enemas at home. Some human enema preparations are lethal to cats, and giving an enema at home risks perforating the bowel
• No mineral oil or paraffin by mouth. It is easily inhaled and causes a serious pneumonia
• No milk. It causes diarrhoea rather than resolving constipation, and adds dehydration
• No forcing or manual attempts to remove anything

See a vet if

• Nothing passed for more than two days
• Repeated unproductive straining, in any animal
• Vomiting, lethargy or refusing food alongside it
• A hard, distended or painful abdomen
• Blood in or around the stool
• Crying while straining
• It keeps recurring, which means the cause has not been found
• Any straining male cat, immediately

What a vet does

Establishes first whether it is bowel or bladder, then whether there is an obstruction. That usually means examination, sometimes X-ray, and often fluids, because dehydration is both cause and consequence.

Treatment ranges from fluids and a laxative through to enemas under sedation and, in severe impaction, manual removal under anaesthetic. Recurrent cases in cats are investigated for megacolon, where the bowel has stretched and lost function, which is managed long term rather than cured.

Preventing recurrence

Water is the main lever, and for cats that mostly means wet food. Beyond that: adequate fibre, keeping weight and activity reasonable, grooming long coats, keeping litter trays clean and plentiful, and treating pain that makes the posture uncomfortable, since arthritic older animals frequently become constipated for that reason alone.

Constipation is easy to treat early and becomes a sedated procedure when left, and the reason it gets left is that straining looks like something an animal will sort out overnight. In a male cat, that assumption is the most expensive one available.

Consultations, diagnostics and emergency treatment are covered on Skeepy Pet HMO plans at any vet clinic in Nigeria, which makes checking whether a straining cat is blocked a same-day decision rather than a wait-and-see.
