Diabetes in Cats & Dogs


Diabetes Mellitus is a medical condition where there is an excessive amount of glucose (sugar) in the blood. This is caused by a deficiency of the hormone insulin, which is secreted by the pancreas. Insulin helps the body use glucose as an energy source. Diabetes Mellitus is an uncommon disease in cats and is seen more frequently in overweight, middle aged to older cats, and is more common in males than females.

Common clinical signs of diabetes are:

  • Increased drinking
  • Increased urination volume
  • Increased appetite
  • Weight loss

Clinical signs start to show as a result of high concentrations of glucose in the blood, and the inability of the body to use the glucose as an energy source.

A diagnosis of diabetes cannot be made on a single blood and urine sample as other conditions, such as stress, can cause a rise in glucose levels. Another blood test called a fructosamine test, can be performed which measures the average of blood glucose levels.

How is Diabetes Mellitus treated?

Diabetes Mellitus is a long term treatable condition usually managed with giving insulin injections twice a day. Regular veterinary check-ups to test blood glucose levels are then required to make sure the insulin dose is effective.


There are two forms of diabetes in dogs; diabetes insipidus and diabetes mellitus. Diabetes insipidus is sometimes called 'drinking diabetes' and diabetes mellitus is also known as 'sugar diabetes'. Diabetes insipidus is a very rare disorder that results in failure to regulate body water content. Diabetes mellitus is more common in dogs, and is frequently diagnosed in dogs five years of age or older... Read more...

Sheba gets her zest back!

Sheba had been losing weight and had increasing disinterest in food when she came to see us. Her owner feared the worse because Sheba, a German Shepherd, was getting old and had really lost her zest for life. Her initial examination did not inspire much hope - a large mass was palpable in her abdomen and blood tests demonstrated markedly high liver pathology. The situation seemed grim as older German Shepherds with abdominal masses are known to have poor outcomes. However, a true scientific approach demands that the problem is defined more accurately. Abdominal radiographs confirmed the presence of a large mass, but it was the following ultrasound examination that gave us the most information. Read more...


At Collaroy Vets, we are equipped with an endoscope. Endoscopy allows a visual examination of internal organs and body parts without invasive exploratory surgery. Endoscopy is performed with either a rigid or flexible fiberoptic instrument. Flexible endoscopes such as those used in the examination of the stomach consist of a long, flexible insertion tube with a bending tip at the end that enters the body, an eyepiece, and a control section. The tip of the endoscope is manipulated using a control knob in the hand piece. In addition to the fiber bundles which provide the light source, two channels are present within the endoscope. One channel permits various endoscopic tools to be passed and fluids to be suctioned or samples taken. The other allows air or water to be passed into the stomach/intestine to insufflate (inject air into the area), or wash away mucus from the viewing port. Special video cameras can be attached to the endoscopes which allow viewing of the exam on a television screen, as well as recording the exam on video. Read more...

Community Update

Many of our local schools run year 10 work experience programs. At Collaroy Vets we are supporters of the high school work experience program and offer places to students from several of our local schools, including Pittwater High and Northern Beaches Secondary College. Work experience is part of the schools' educational program where students experience the world of work, often for the first time. It is the short term placement of secondary school students with employers, to provide insights into the industry, and the workplace in which they are located. Students are placed with employers primarily to observe and learn - and can be a great way to test drive careers. We offer the student insight into several careers in animal care including Veterinary Science, Vet Nursing and Practice Management. Read more...
