What this means
A healthy cat often rests with its paws tucked under it, but it is relaxed and alert, its eyes are open and it reacts to what is going on. A hunched cat looks different: the back is rounded, the belly drawn in, the head lowered, the eyes half closed, it sits in the same spot for a long time and does not want to play or eat. If you see this posture, it is worth taking a photo or a video.
This posture most often points to belly pain or feeling unwell: a digestive upset, constipation or a blocked gut, but it can also mean pain in the bladder, a fever, trouble breathing or pain elsewhere. Because cats hide pain, this is a serious sign even if the rest of the behaviour looks almost normal.
Notice whether the cat is also vomiting, eating, drinking, passing stools and urinating, and whether it lets you touch the belly or hisses and pulls away. Do not press on the belly and do not give anything at home instead of an examination. A hunched cat should always be examined by a vet.
Possible causes
These are things that can cause this sign. It is not a diagnosis, and they are not equally likely for your cat.
-
Belly pain from a digestive upset
Inflammation of the stomach or gut, nausea or gas can cause pain that makes a cat hunch. Vomiting or diarrhoea may come with it.
-
Constipation or a blocked gut
Stools held back, or a swallowed object blocking the gut, stretch the belly painfully. The cat may strain and not eat.
-
Pain in the bladder or urinary tract
Urinary problems also make a cat hunch, and it may keep visiting the litter box. A blocked urinary tract is life-threatening.
-
Pain elsewhere, or a fever
An infection, an injury or joint pain can cause the same posture. The cat avoids moving and hides.
-
Difficulty breathing
When breathing is hard, a cat sits hunched with its neck stretched out and its elbows pressed in. Such breathing needs urgent examination.
What else to watch for
These observations help your vet build the picture faster. Note down what you saw and when.
- How long it has sat like this and whether it wants to move
- Whether it eats and drinks, or vomits
- Whether it passes stools and urine, or strains in the litter box
- How it reacts when you touch the belly: hisses, pulls away or cries out
- Whether it breathes fast or with effort
- Whether it hides or avoids contact
When to book a routine visit
A hunched cat should always be examined by a vet. If the posture lasts more than a few hours, or the cat is not eating or is hiding, contact a vet the same day, and go immediately if any of the signs above are present.
Related conditions
Conditions whose entries mention this sign. The list is somewhere to read on, not a way to reach a diagnosis.
- Gastrointestinal conditions Digestion and liver A general name for upsets of the stomach and intestines: a cat vomits, has diarrhoea or constipation, or loses its appetite. Some pass quickly while others point to a more serious illness, so it matters how long they last.
- Pancreatitis Digestion and liver Inflammation of the pancreas, a gland beside the stomach and gut. In cats it can show only as a few vague signs, such as listlessness and a lost appetite, so it is easy to miss.
- Feline panleukopenia (feline distemper) Infections A highly contagious viral disease that attacks the gut and the bone marrow, so the number of white blood cells in the blood suddenly drops. It is especially dangerous for kittens and can become life-threatening within a short time.
- Urethral blockage Kidneys and urinary tract A condition in which the urethra, the narrow tube that carries urine out of the bladder, is blocked by a plug or a small stone, and the cat can no longer pass urine. It is an emergency that can threaten life within hours.
