The graph shows the blood glucose results obtained from a 6 kg diabetic cat which is being treated in hospital with 20 U of lente insulin once daily. Normal blood glucose concentrations would be between 3.5–7.5 mmol/l (63–135 mg/dl).
| Question | Answer | Article | |
| What is the assessment of this case? | The glucose curve suggests that the cat is insulin resistant. |
Link to Article | |
| What differential diagnoses need to be considered? | Mild insulin resistance can be seen with a variety of physiological and pathological conditions including dioestrus, pregnancy, and severe obesity.
Affected cats generally demonstrate variable or continuously poor control of their diabetes. |
