Constipation in cats means the colon is not moving stool through normally. Feline constipation can range from mild difficulty to complete obstruction. Cats typically defecate once a day, though defecating once every 36 to 48 hours can be normal for some individuals.<\/span><\/p>\n A cat that hasn’t passed a stool in 48 hours or is straining in the litter box is likely constipated. <\/span>Obstipation (complete inability to pass stool) is the more severe form and requires immediate veterinary care at the <\/span>nearest cat hospital<\/span><\/a>.<\/span><\/p>\n Understanding cats and constipation starts with feline biology. Cats evolved as desert animals with a naturally low thirst drive. They are designed to get most of their moisture from prey, not from a water bowl.<\/span><\/p>\n Feline constipation is especially common in indoor cats eating primarily <\/span>dry food<\/span><\/a>. The colon compensates for low water intake by extracting more moisture from stool, producing hard, dry stools that are difficult to pass. With low activity levels and litter box stress, feline constipation becomes very common.<\/span><\/p>\n Beyond dehydration and diet, contributing causes of feline constipation include:<\/span><\/p>\n Cat constipation symptoms can build gradually over several days. Watch for:<\/span><\/p>\n Feline constipation symptoms are sometimes confused with a urinary blockage, which is also an emergency. If you are unsure which is happening, see the <\/span>nearest cat doctor<\/span><\/a> immediately.<\/span><\/p>\n Physical examination and abdominal palpation usually reveal a colon packed with hard stool. A rectal examination assesses stool consistency and checks for masses or narrowing.<\/span><\/p>\n X-rays confirm the degree of colonic impaction and identify any structural causes. <\/span>Cat blood tests<\/span><\/a> check kidney values, electrolytes, and thyroid function.<\/span> Ultrasound is used when a tumour or foreign body is suspected.<\/span><\/p>\n Treatment depends on severity, cause, and how long the cat has been constipated.<\/span><\/p>\n Switching to wet food is one of the most effective first steps. Wet food is approximately 75-80% moisture, compared with around 10% in dry food. Offering a cat water fountain can also significantly increase voluntary water intake.<\/span><\/p>\n A vet may recommend plain psyllium fibre or a hairball-control diet, depending on the cause. These changes support softer stools and more regular bowel movements.<\/span><\/p>\n Cat constipation medicine is prescribed based on severity and cause. Options include:<\/span><\/p>\n A vet may also perform an enema for moderate constipation. Do not attempt an enema at home. Human-formulated phosphate enemas are toxic to cats and can be fatal. Only vet-administered, cat-safe enemas are appropriate.<\/span><\/p>\n Severe obstipation requires manual deobstipation under general anaesthesia. Refractory megacolon may require subtotal colectomy, a surgical procedure to remove the non-functional section of the colon.<\/span><\/p>\n The impact of constipation on cats escalates quickly when left unmanaged. Repeated straining inflames and stretches the colon wall. Over time, the colon loses its contractile function. This progression to megacolon is difficult to reverse.<\/span><\/p>\n Other risks of untreated feline constipation include:<\/span><\/p>\n Prevention focuses on hydration, diet, and a consistent routine:<\/span><\/p>\n Feline constipation is manageable when caught early. Waiting too long turns a dietary problem into a structural one, and structural problems are far harder to treat.<\/span><\/p>\n If your cat hasn’t passed a stool in 48 hours or seems uncomfortable, book a pet consultation. A vet can assess what’s going on and recommend the right treatment.\u00a0<\/span><\/p>\n The cat’s symptoms of constipation include straining in the litter box, hard, dry stools, and repeated failed attempts to defecate. Reduced appetite, lethargy, and vomiting may also develop. A firm or swollen abdomen is a sign to seek vet care promptly.<\/span><\/p>\n Yes. Obstipation is a veterinary emergency. Constipation that causes repeated vomiting, significant pain, or abdominal swelling also needs urgent care.<\/span><\/p>\n Wet food is the most useful dietary change. Plain unsweetened pumpkin (a teaspoon mixed into food) provides soluble fibre and moisture. Plain psyllium fibre can also help under vet guidance.<\/span><\/p>\n Most healthy cats defecate once a day. Some naturally go every 36 to 48 hours without any problem.<\/span><\/p>\n Collier, A.
