Umbilical hernia in cats: causes, symptoms and prevention

• kittens of breeds predisposed to congenital abnormalities;
• animals with weak connective tissue;
• cats with an inherited defect.

Evidence on breed-specific risks and the precise frequency of umbilical hernias in cats is limited. A breed name or connective tissue thought to be weak is therefore not a diagnosis. The kitten is assessed as a whole, and a navel swelling is investigated even without a known family history.

A hernia is usually easy to identify on clinical examination. Further assessment may include:

• examination of the abdominal wall by touch;
• ultrasound if internal organ involvement is suspected.

The vet asks when the swelling was noticed, whether it has grown and whether there is pain, vomiting or appetite change. The abdominal wall opening, contents and possible reducibility are examined gently. The diameter of the lump beneath the skin is not the same measurement as the actual hernia opening.

Ultrasound may be used if the contents or connection to the abdomen are unclear. X-rays or other tests may be considered according to symptoms. Not every small, clearly identifiable umbilical hernia needs the same imaging series. General health is also assessed when planning surgery.

Not every navel abnormality is simply a hernia. Tell the vet if it remains wet, leaks fluid or the surrounding skin is irritated. In a rare developmental disorder, the foetal connection between the bladder and navel remains open. Investigation and treatment differ from an ordinary fat-containing hernia.

The vet chooses tests and an anaesthetic plan according to age, health and the procedure. Mention medicines, previous diseases and any eating or growth problems. Assessment includes hydration, breathing and circulation, with blood tests according to individual need.

Ask for instructions specific to your cat on food, water and medicines before surgery. Do not apply a prolonged adult-cat fast to a kitten yourself. If you suspect strangulation, do not delay contact because the kitten has not fasted: the emergency practice will advise according to the situation.

Arrange a quiet recovery area and restrict jumping, vigorous play and outdoor access as instructed by the surgeon. Avoid unnecessary strain on the abdominal wound. Your cat may become brighter before it is strong enough, so do not end restrictions simply because they want to play.

Keep the wound dry and prevent licking or scratching with prescribed protection where needed. Do not apply creams or disinfectants without veterinary instructions. Monitor the edges, swelling, redness and any discharge. Increasing swelling, bleeding or other discharge, odour or wound opening warrants contact.

Monitor appetite, alertness and whether movement is as expected for the recovery stage too. Although tiredness can follow anaesthesia, your cat should be rousable. Unusual weakness, repeated vomiting or deterioration must not be dismissed at home.

Ask for written pain relief, follow-up and possible stitch-removal instructions. Not every stitch needs removal, so do not pull stitches out yourself. If giving medicines or protecting the wound is difficult, the practice can help adapt arrangements.
