Prescription Diabetes Medicine & Insulin for Cats

Help manage feline diabetes with diabetes medicine & insulin. Chewy carries many diabetes treatment options, including insulin and prescription diabetes medication that can be given orally or transdermally.

Only your vet can diagnose diabetes and prescribe a proper treatment regimen for your cat. Your veterinarian will perform certain tests to determine the extent of the issue and may suggest a dietary intervention before starting a prescription medication.

Treatments for diabetes often include insulin injections you give your cat at home. Some vets may prescribe an oral or transdermal diabetes medication like glipizide instead of insulin, depending on the severity of the disease and whether you can adopt an insulin injection treatment regimen. Younger cats with the disease may require insulin & diabetes medicine in an adjusted dose.

Diabetes can predispose your cat to secondary issues like infections, so your vet may prescribe other prescription medicine, like antibiotics, to help with these. You can order antibiotics along with your diabetes medications, syringes, and glucose testing supplies in the Chewy pet pharmacy, plus we carry diabetes medicine & insulin for dogs with diabetes, too. Check out our selection of diabetes medicine & insulin online at Chewy.com—we have many of the major brands and generics and lots of other supplies for your diabetic cat!

Frequently Asked Questions about Prescription Diabetes Medicine & Insulin for Cats

What is the best prescription cat diabetes medicine?

The best prescription diabetes medicine for your kitty should be determined by your vet. Vetsulin and ProZinc are commonly prescribed for cats, but brands like Lantus may be suggested instead. Some vets will prescribe an oral or transdermal diabetes medication instead of insulin, especially if at-home insulin therapy is not possible. Low-carb diets can sometimes be a successful intervention, with or without insulin therapy, as well. Talk to your vet about all your options and follow the recommended treatment protocols closely.

What are the signs that my cat has diabetes?

The signs that your cat may have diabetes include excessive thirst and urination; weight loss despite increased appetite; inability to jump; lethargy; and lack of appetite or vomiting. See your veterinarian if your cat exhibits any of these symptoms, as they may signal diabetes or another serious illness.

How do I get cat diabetes medicine and insulin prescriptions online at Chewy Pharmacy?

Get cat diabetes medicine and insulin prescriptions online at Chewy Pharmacy by getting an exam, test, and prescription from your vet. Then, go online and add the appropriate prescription product to your cart. At checkout, you will be able to add your pet’s name and vet contact info so Chewy can verify the prescription on your behalf. That’s all you need to do to order your prescription feline diabetes medication online.

How do I give my cat an insulin shot?

Give your cat an insulin shot by following the instructions given to you by your vet. You will need to draw up the right dose into the syringe and then inject it into a fold of “tented” skin you lift on your cat’s back or shoulders using your thumb and forefinger. Inject at a 45-degree angle and make sure you don’t just shoot it onto the fur. Your vet can demonstrate the correct technique and suggest tips for making the process easier. You can find instructional videos online to help you, as well. Always give insulin shots after your cat has eaten to avoid dangerous blood sugar drops.

How do I set up Autoship for my prescription cat diabetes medicine and insulin?

Set up Autoship for your prescription diabetes medicine and insulin by selecting Autoship when you check out. Then, choose the frequency of your deliveries. Once you set up Autoship, you can cancel or change your preferences any time you want. You must have a valid prescription or refills on file with Chewy for Autoship deliveries to occur. If we do not have a prescription, or if your prescription is expiring soon, one of our team members will reach out to your vet to obtain the necessary information. You can always have your cat’s diabetes medications on hand with Autoship from Chewy!
