"What Leon and I are trying to do is drive to keep your pets in optimal health. This is not a necessity for humans - we don't sniff around in the dirt, we don't need to be wormed or defleaed - whereas pets, it's a basic healthcare requirement."
Their online subscription service lets customers select their pet's size and weight and specific products which are then delivered to their door every time their pet is due for another treatment.
Vetty is owned and operated by a registered veterinarian so the treatments are broken up to the exact doses that the pet needs.
Walker said this removed any confusion owners may have selecting products when visiting the vet or buying online as Christensen has selected and put together products he trusts.
Joined by business partner Jason Meuli to help kick start the business, Vetty has been up and running since the beginning of the year and now serves thousands of pets nationwide.
They only cater to cats and dogs but Walker said they were looking to increase their offerings to other pets and healthcare products in the near future.
