The Ultimate Guide to Creating a Pet Time Capsule (And Other Pawsome Memory-Keeping Ideas)

As another year winds down, I find myself watching Jax and Milan—my two rescue critters—sharing the couch in their usual cuddle puddle.


Jax, my giant, goofy mutt, is sprawled upside down, using his tiny feline brother Milan as a pillow. Most cats would protest, but Milan—who clearly missed the memo about cats being aloof—is purring away contentedly. He's our little cat-who-thinks-he’s-a-dog and insists on joining every walk and car ride with his big brother.


Both boys came from uncertain beginnings, but now they're the stars of our daily family comedy show. Watching them snooze together, I'm struck by how many precious moments we've collected this year alone. Which got me thinking: why not create something special for our future selves to remember these times?

Why Create a Pet Time Capsule?

Think of it as a treasure chest of tail-wagging memories, a paw-some collection of moments frozen in time. It's like a time machine for the heart, but with more fur and slobber involved. When future-you opens this capsule, you'll get to relive all those precious moments that make pet parenthood so special.

The Ultimate Pet Time Capsule Guide

Essential Items (The Basics)

The Purr-fect Container


  • Choose something waterproof and airtight
  • Consider size based on your collection
  • Pro tip: I used an old cookie tin—the perfect size for Milan to curl up and take a nap in before we filled it


Memory Preservation Ideas

Physical Mementos


  • A lock of fur or feather (labeled with date and location—“Jax's summer shed")
  • Paw or claw prints (for tips, check out this blog post about making paw print art)
  • Their favorite toy (or a photo if they're like Milan, who guards his catnip mouse like it's Fort Knox)
  • An old collar or harness
  • An old worn out name tag or copy


Written Treasures


  • A “day-in-the-life” journal entry (check out my Pawsome Journals for a year’s worth of prompted journal writing!)
  • Their “favorite things” list
  • Funny quirks and habits
  • Special nicknames and why you chose them
  • A letter to your future self about your life with your pet right now
  • Training milestones (Jax's proudest achievement this year: learning to "leave it" when we brought home Milan—and his enticing food bowl—for the first time)


Photo Collections


  • First day home
  • Favorite sleeping positions
  • Holiday celebrations
  • With their best animal friends
  • Candid moments with family

When to Open Your Time Capsule

Choose a meaningful date:


  • A gotcha day anniversary
  • A special birthday
  • When they've mastered a particularly challenging trick (still waiting on Milan to learn “sit”)

Tips for Preservation

  • Use acid-free paper for documents and photos
  • Store in a cool, dry place (or a very sealed, waterproofed container if it’s going to be stored outside)
  • Make digital copies of everything
  • Label everything with dates and descriptions
  • Consider vacuum sealing important items

Hide your time capsule someplace fun and meaningful (like in the garden) or safe (like on the top shelf in your closet)—it's up to you!

Beyond the Time Capsule: More Pet Memory-Keeping Ideas

1. The Quote Journal

Keep a small notebook handy to write down things you find yourself saying to your pets. My current favorite: "Jax, relax! Roomba isn't trying to steal your fur.”


2. The Seasonal Photo Shoot

Create a tradition of taking photos in the same spot every season. Both Milan and Jax have perfected their poses with their "I'm only doing this because you have cheese” faces.


3. The Birthday Box

Similar to a time capsule but opened annually on their birthday. Include predictions about what they'll be up to next year!


Every moment with our pets is precious, even the ones where they're attempting to redecorate our homes with shredded toilet paper (looking at my sister’s three kittens!) or judging our life choices from atop the refrigerator (Milan's specialty). These time capsules help us capture not just the big moments, but all the little ones that make our hearts full.
