Insulin therapy

Diabetes mellitus is caused by a lack of available insulin. Your diabetic cat’s insulin level can be restored with daily insulin injections.

Veterinary insulin is specifically formualted for use in diabetic dogs and cats. Read more about insulin.

Looking after your diabetic cat’s insulin

Insulin is a fragile substance. Incorrect storage and use of insulin may mean that it does not have the proper effect when given to your cat.

  • Insulin must always be kept in the fridge – only remove it when drawing up an injection.
  • Insulin must not be frozen – freezing destroys insulin.
  • Always store the insulin in an upright position.
  • Gently invert the vial a few times before use to re-suspend the insulin.
