The Importance of Insulin

If your cat has developed diabetes, it might not be controllable via diet, making insulin vital. Insulin is a hormone in the body that converts sugar into energy. Diabetes makes it so this hormone is either unable to be used by the body properly or results in the body not making enough insulin to achieve what’s needed. The result is high levels of blood sugar and a host of health issues.

Unfortunately, there’s no cure for diabetes, but it can be treated with synthetic insulin. Using insulin means your cat’s blood sugar levels can be regulated, which will improve the state of your pet’s health.

There are four main types of insulin used in cats:

  • Vetsulin
  • PZI
  • Lantus
  • Humulin

How Much Does Insulin Cost?

How much insulin costs will vary, depending upon which brand you use. Whether or not you go with a generic medicine will also affect the cost. Generic medicines work equally as well as name brands; they have the same ingredients and do the same thing, but they simply cost less. How much insulin your cat requires each month will also affect your costs.

Generally, most felines will need $50–$60 of insulin every 30–40 days, but those with a less severe form of diabetes will only need roughly $20–$30 of insulin in that same period. But depending on which brand you go with, you can expect to pay $30–$100 monthly for insulin.

Those prices are mostly for insulin that is injected with syringes, but injection pens have become more popular recently. These pens make injecting insulin easier and cost approximately $150 for the pen, with refills being about $50 for a box of 100.

Additional Costs to Anticipate

Insulin isn’t the only thing you’ll be purchasing to manage your cat’s diabetes, though. You’ll need supplies to routinely test your feline’s blood sugar level; these will cost $25–$50. Then there are vet visits, so your vet can check your kitty over routinely. Depending on your vet and your geographical location, these can cost $50–$100 a visit.

You’ll also likely need to change your cat’s diet, possibly with a prescription diet. Prescription foods can be pricier than regular old cat food, so you’re looking at $40–$80 each month for this.

Other additional costs to consider are the ones associated with complications arising from your feline’s diabetes. For example, cataracts aren’t uncommon in cats with diabetes, and cataract surgery can cost up to $3,500. Uncontrolled diabetes can also lead to kidney disease ($2,000 to $4,000), pancreatitis ($3,000 to $5,000), and liver disease ($2,000 to $5,000). Many of these complications will be less likely to occur by following your vet’s instructions on providing your pet with insulin and making lifestyle changes, though.

How to Save on the Cost of Diabetes Care

There are absolutely ways you can save on the costs associated with treating your cat’s diabetes.

A few of these recommendations are:
  • Use generic medicine instead of name brand.
  • Purchase insulin online, as it may be cheaper there than at your veterinarian’s office.
  • Purchase insulin in bulk; doing this may enable you to get a discount.
  • Shop around and check prices before committing to purchasing anything.
  • See if your pharmacy has a benefits plan.
  • Ask your vet for a care plan that requires fewer vet visits.
  • Invest in a good pet insurance plan.

Does Pet Insurance Cover Insulin?

Purchasing an excellent pet insurance plan for your feline can save you a bundle in the long run when it comes to caring for diabetes. Most plans will cover diabetes care in some form, but whether insulin is covered will vary by company and plan. Insulin coverage may only come in the form of an add-on of some kind, while the regular plan covers vet visits and prescription diets. And some plans may put a cap on how much is allowed for diabetes coverage each year.

The biggest issue you’ll run into with pet insurance and diabetes is if your cat has been diagnosed with the disease before an insurance plan is purchased. If that’s the case, diabetes will be considered pre-existing and won’t be covered by insurance.
