Tim Wilson, owner and developer of Pet Royals, and his wife, singer/songwriter and author Amy Robbins-Wilson, will be at the Saturday, Sept. 15 Whisker Walk and Family Fun Day in Harbor Park for a couple of good reasons.

The pair have adopted several animals from the Humane Society of Knox County, including their cats Cleo and Tux. The cats are spokespeople, as it were, for Pet Royals, demonstrating the Apple application’s ability to transform photos of pets to reveal the royalty within.

Pet Royals by CAT Game Apps LLC of Belfast is a photo app that lets users dress their pets in everything from crowns to crown jewels. For those who prefer an Egyptian twist, there is an upgrade to add accents from the land of the pharaohs. The app is easy to use, yet quite versatile. Users take a photo of a pet’s face with their Apple device; choose the accessories they want to add to the photo; and adjust the size and orientation of the accessories using their fingers. And if the royal pet has something to say, adding a text bubble is simple. There also is a drawing tool to draw on some eyeliner or other accent.

When the image is complete, owners have several options such as saving it to their camera roll, emailing it to a friend, sharing it on Facebook or Instagram or posting it as a meme to Pinterest. Users also can upload the photo to Shutterfly to make gifts, cards, invitations, calendars or more.

“Our goal is to help pet lovers have fun with their pets without bothering the animal. We are also hopeful that shelters will use the app to make fun pictures for ads so that shelter animals get more attention,” said Wilson, owner and developer of Pet Royals.

The basic version of Pet Royals is free and is currently available on iPhone and iPad; for more information, visit PetRoyals.com. The Belfast couple will be demonstrating it as a fundraiser at the Whisker Walk to raise money for the shelter.

“We look forward to taking pet photos and giving them the royal treatment for donations,” said Wilson.

The Whisker Walk and Family Fun Day, formerly the Thomaston-based Fur ‘n’ Foliage Dog Walk, will begin with walk registration at 9:30 a.m.; the walk commences 10:30 i.e. and other activities including an agility course, demos, raffles, live music and food and other vendors will run to 2 p.m. For more information, visit hskcme.org or call 594-2200.
