Coughing cats

At first Gus’s carer thought he had hair balls. So did the friends she asked. He gagged and convulsed and brought up froth. She gave him some laxative paste.

Everything in the litter tray seemed normal and for a while Gus seemed OK.

When she rushed off to work he was curled up on the lounge in the sun room as usual.

But the gagging started up again, especially at night. She noticed that he wasn’t eating all his dinner and sometimes he stopped in the middle of the gagging and breathed heavily.

One night he crept on to the end of the bed and wheezed and gasped for breath until she was sure he was choking to death.

Next morning she rushed him into us. We X-rayed his chest and found a very hazy lung and signs of chronic bronchitis.

We took samples from Gus’s lungs and found he had pneumonia. Gus had developed an airway and lung infection on top of the chronic bronchitis.

Cats get asthma and bronchitis, just like humans do. For some it is worse when there are lots of pollens blowing about, for others being cooped up inside with the stagnant air and dust mites in winter set the wheezing and coughing off.

His carer remembered that he had always had a bit of a wheeze, especially in spring and early summer. She hadn’t thought much of it.

It is very easy to confuse coughing with vomiting or regurgitation. Usually food or bile will come up at some stage with vomiting. Vomiting cats often lose their appetite or have diarrhoea as well. Coughing cats don’t go off their food unless they develop an infection as well.

Some asthmatic cats have life threatening breathing difficulties if they are not treated adequately. If you notice your cat coughing, gagging, breathing with difficulty, especially with the mouth open and the neck extended, contact your vet.

Gus is back to his irascible self after a long course of antibiotics. He’s getting used to a puffer and spacer, and quite likes all the attention we give him.

Haemorrhagic gastroenteritis

Dogs affected with haemorrhagic gastroenteritis (HGE) vomit and pass diarrhoea with blood in it.  It develops rapidly and sometimes owners just find their dog collapsed.

HGE is more common in small breeds of dogs. A very high red blood cell concentration, measured as the packed cell volume, PCV, or haematocrit is characteristic of HGE. Most normal dogs have hæmatocrits of 37-55%. Dogs with HGE have hæmatocrits over 60%.

We don’t know the exact cause of HGE.

We rule out other causes of vomiting and bloody diarrhoea while we start emergency treatment for HGE.  These causes include stomach ulcers, trauma, worms, other gut parasites, gastrointestinal tumours, intestinal obstruction, foreign bodies, parvovirus, and coagulation disorders.

Dogs with HGE are very ill and if left untreated die. In most cases, it runs its course in a few days with intravenous fluid therapy to combat the dehydration and shock. We give other treatments like antibiotics, anti-ulcer medication and corticosteroids as indicated.

If intravenous fluid therapy is not given the haematocrit continues to rise and the blood becomes so thick that it can hardly flow. A clotting disorder called disseminated intravascular coagulation develops which is often irreversible and fatal.

Pancreatitis

Fatty foods like sausages, cheese and the cat’s biscuits, cause acute pancreatitis in overweight middle-aged dogs.

Dogs with acute pancreatitis vomit, refuse their food, withdraw from the family and show signs of pain in the belly.  They hunch over, adopt a praying position, or are reluctant to move.

To treat pancreatitis we ban all food  and give intravenous fluids, antibiotics, anti-inflammatory drugs and pain relief. The pancreas produces enzymes that digest food, and hormones like insulin that help the body utilise glucose.

Under normal conditions, digestive enzymes produced by the pancreas are activated when they reach the small intestines. In pancreatitis, these enzymes are activated prematurely and digest the pancreas itself. The severity of the disease depends on the quantity of enzymes activated.

Some cases of pancreatitis are in reaction to particular medications or toxins.

Inflammation of the pancreas sometimes allows digestive enzymes to spill into the abdominal cavity resulting in damage to surrounding organs, such as the liver, bile ducts, gall bladder, and intestines.  Toxins spilling into the bloodstream cause shock and problems in more distant organs.

If we suspect pancreatitis we check the level of pancreatic enzymes in the blood. Some dogs with pancreatitis have normal enzyme levels. If we still suspect pancreatitis we run a pancreatic specific lipase test.

Recovery depends on the extent of the disease and the response to initial therapy. Dogs that present with shock and depression have a very guarded prognosis. Most of the mild forms of pancreatitis respond quickly to treatment and have a good outlook.

Most dogs recover with no long-term ill-effects. However, there are three possible long-term complications of severe or repeated pancreatitis.

  1. If a significant number of cells that produce digestive enzymes are destroyed, proper food digestion is compromised. The dog loses weight despite a ravenous appetite and produces voluminous, soft faeces.  This is known as pancreatic insufficiency and is treated with by adding the missing enzymes to the food.
  2. If the cells that produce insulin are destroyed diabetes mellitus can result.  Signs of diabetes include weight loss despite a good appetite coupled with excessive drinking and urination.  Insulin therapy may be necessary.
  3. In rare cases, adhesions between the abdominal organs cause momentary “catches” as your dog moves are a consequence of pancreatitis.
  4. After a bout of pancreatitis, dogs are prone to relapse and owners must make sure that their dog has no access to fatty foods. We recommend a low fat good quality dog food.
