Guinea Pig Appreciation Day
In the Obscure Holiday Calendar app, Guinea Pig Appreciation Day 🐹 includes custom visuals, smart reminders, and fast share links.
Overview
Guinea Pig Appreciation Day is observed annually on July 16th, honoring the small, gentle rodents that have won over millions of pet owners worldwide. The date was chosen by Piggles Guinea Pig Rescue, a Toronto-based rescue founded by Caroline Lane, using an alphabet code: G is the 7th letter (July) and P is the 16th (the 16th day). Despite their name, guinea pigs aren't pigs and aren't from Guinea — they're rodents native to the Andes Mountains of South America, domesticated by Indigenous peoples thousands of years before European traders introduced them to the continent that gave them their misleading English name. The day is a chance to celebrate their quirks, from their distinctive high-pitched "wheek" to their long history alongside humans, and to encourage adoption from rescues over impulse purchases.
Origin and story
Guinea Pig Appreciation Day was created in 2016 by Caroline Lane, founder of Piggles Guinea Pig Rescue, a foster-based rescue and rehoming service in the Greater Toronto Area that has helped nearly 1,300 guinea pigs since it started in 2009. Rather than tying the day to a historical event, Lane picked the date with a simple alphabet code: G is the 7th letter of the alphabet, for July, and P is the 16th, for the 16th day — spelling out "GP" in the calendar itself.
The animals being honored have a much longer history than the holiday. Guinea pigs were first domesticated thousands of years ago by Indigenous peoples in the Andes Mountains of South America, who raised them for food and used them in religious ceremonies long before European traders brought them across the Atlantic in the 16th century. Once in Europe, their round shape and piggy little squeals earned them an English name that has nothing to do with where they actually come from — they're not pigs, and the leading theories for "guinea" trace back to Guiana, West Africa trade routes, or simply Europeans' habit of using "Guinea" as shorthand for any far-off, exotic origin.

Ways to celebrate
Piggles Guinea Pig Rescue created this day to promote proper care and adoption, so the most on-theme ways to mark it go beyond just admiring photos online.
Visit or support a rescue
Guinea pig-specific rescues like Piggles exist because so many are surrendered after impulse pet-store purchases. A visit, a small donation, or fostering a pair goes further than buying from a breeder.
Learn the basics of proper care
Guinea pigs are herd animals and shouldn't be kept alone — most welfare organizations recommend housing them in same-sex pairs or small groups, with a diet built around unlimited hay, fresh vegetables, and a vitamin C source, since (like humans) they can't produce it themselves.
Spend time with one, or adopt
If you already share your home with a guinea pig, today's an easy excuse for extra veggies and lap time. If you don't, treat the day as a nudge to research what real care involves before bringing one home.

Fun facts
- Guinea Pig Appreciation Day was created in 2016 by Caroline Lane, founder of Piggles Guinea Pig Rescue in Toronto, Canada, which has helped rehome nearly 1,300 guinea pigs since 2009.
- The July 16 date comes from a simple alphabet code: G is the 7th letter of the alphabet (for July) and P is the 16th (for the 16th day).
- Guinea pigs are rodents, not pigs — their scientific name, Cavia porcellus, comes from the Latin "porcellus" ("little pig"), a nod to their round shape and piggy squeals.
- They're the only rodents known to make a "wheek" — a high-pitched squeal used specifically to get a human's attention, a behavior scientists believe developed only after domestication.
- Guinea pigs have been kept by humans for thousands of years, first domesticated by Indigenous peoples in the Andes for food and ceremonial use, and later studied in labs since the 1600s — which is where the idiom "guinea pig," meaning test subject, comes from.
