Online Pet Pharmacies For Cats
Written by Laura Hall

If you’re looking for a more convenient way to get your cat’s prescriptions or somewhere to buy over-the-counter meds, why not try an online pet pharmacy? 

The vet office doesn’t always have prescriptions in stock, and their selection of non-prescription medication tends to be limited. Online pet pharmacies allow pet parents to browse different options and get exactly what they need sent straight to their doorstep. 

With so many around all claiming to be the best, it’s tough to know which ones actually are, so we’ve made a list of our 8 best online pet pharmacy recommendations to help you out. Let’s take a look at our top picks starting with 1800PetMeds and Chewy Pharmacy

Cat with medication from online pet pharmacy


How do online pet pharmacies work?

Online pet pharmacies work the same way as human ones. You can order the medication you want to be delivered straight to your home. To prove your cat’s prescription, you may have to upload a photo of it at the checkout and/or give your vet’s info so that it can be verified. 

What can you order from online pet pharmacies?

You can order prescription medications like antibiotics and over-the-counter medications like flea and tick treatments, as well as holistic products like vitamins & supplements, and often everyday supplies like food and grooming products, too.

Are online pet pharmacies safe?

Licensed and accredited online pet pharmacies are perfectly safe, but you must stick to recognized pharmaceutical websites and never buy medication from third-party sellers. Things can also get damaged in the mail, so if your pet’s medication arrives damaged or opened, throw it away.

How do you know if an online pet pharmacy is real?

Real online vet pharmacies are licensed and accredited. If you’re unsure about which one to use, ask your vet for their recommendation or use our list as a guide. 

Is it cheaper to buy cat prescriptions online?

It’s not always cheaper to order your cat’s prescriptions online, but it often is. Most online pet pharmacies also have loyalty programs and points programs, as well as sales, offers, discounts, and deals, especially for bulk & recurring orders.

Can I get pet meds without a vet’s prescription?

You cannot order prescription medication for your cat without a prescription from your vet. 

Can I get a vet prescription online? 

Some vets have options for virtual appointments, but there are also vets that offer exclusively virtual appointments and prescribe medications online. Whilst this may be convenient, we strongly recommend keeping your regular in-person vet for annual check-ups and more serious situations.

Does GoodRx work for animal prescriptions?

Yes! GoodRx now works for pet prescriptions, too.
