Feline Diabetes Symptoms.
How To Recognize Signs of Cat Diabetes

Feline diabetes symptoms vary depending on how far advanced the cat diabetes is.

This page goes through the main signs and symptoms of feline diabetes, so you can become aware of what you should be looking for.

The earlier feline diabetes is diagnosed and treated, the better. The more advanced the disease, the more difficult it becomes to treat, manage and control.

Symptoms of Feline Diabetes

Put very simply, diabetes mellitus (to use the correct term) occurs because the cat is unable to control its blood sugar level. The sugar isn't able to enter the cat's cells and to be used for energy, due to the lack of a hormone called insulin.

The blood sugar rises higher and higher, and as a result sugar will start to be excreted in the cat's urine. The cat will develop a raging thirst, as its body is trying to dilute the sugar, and as a result will produce large amounts of dilute cat urine.

The main symptoms include some or all of the following. These will get worse and more obvious as the disease progresses.

If the cat diabetes isn't treated, the cat will start to break down fat to use as energy (because it can't use sugar). Fat breakdown produces substances called ketones. Once this occurs, additional symptoms start to appear:

  • Cat vomiting
  • Weakness
  • Feline depression
  • Smell of ketones on the cat's breath (these smell sweet, a bit like pear drop sweets or fingernail polish)
  • Rapid, labored breathing

At this point, prompt medical treatment is vital, and is likely to be extensive. It's much better to pick up on the earlier feline diabetes symptoms and get the disease under control well before it gets to this stage.
