Diabetes mellitus is one of the most common endocrinopathy of cats. It is another disease that cats
share with the humans. Diabetes mellitus sets up every age, breed or gender. Certain conditions
predispose a cat to developing diabetes. Overweight, old and male animals are among the risk
groups. An early diagnosis and correct treatment is important to achieve remission. A large increase
of blood sugar and fructosamins confirm the diagnosis of diabetes mellitus. Measuring betahydroxybutyrat
in the blood can also give an information about diabetes mellitus.
Adipositas is the consequence of cats malnutrition. Fat cats seem more likely to come down with
diabetes mellitus than normal weight cats. Not just weight can identify fat cats but also the BCS. The
shape of the body gets judged by a scale from 1 to 9.
Cats that featured a BCS >5/9 showed up with a significantly increased glucose level in the blood
serum (119,09±73,69 vs. 174,56±132,83 mg/dl). Measuring fructosamins and beta-hydroxybutyrat,
both were defined higher by trend than measured in cats´ blood of a BCS<5/9.
Beta-hydroxybutyrat in the blood was influenced by the cat´s activity. Cats that didn´t play (n=7) had
clearly high beta-hydroxybutyrat samples (0,13±0,17 vs. 0,55±0,65 mmol/l). The same happened to
blood sugar, that was also very high (232,14±171,12 vs. 125,36±79,63 mg/dl).
Based on this study it can be assumed that overweight and inactivity predispose diabetes mellitus.
