For many of us, a pet is more than just an animal — it's a lifelong companion, a source of comfort, and a member of the family. When that bond is broken by death, the grief can feel overwhelming.

That’s why more people are exploring options for preserving pets after death. But not all methods offer the same outcome — or intention.

Some seek physical memory. Others seek the possibility of revival. Let’s explore the difference.

‍

Traditional preservation methods

Before advanced science entered the conversation, preservation meant primarily one thing: appearance. The following are commonly used today:

1. Taxidermy

• The pet's skin is removed and mounted onto a custom form.
• Eyes are replaced, and lifelike poses are created.
• The goal is visual resemblance — not biological integrity.

‍

2. Freeze-drying

• The entire pet is frozen and then slowly dehydrated under vacuum pressure.
• Maintains shape and color more naturally than taxidermy.
• Often used for smaller animals like birds, rabbits, or cats.

‍

What they have in common:
Both techniques create a memorial object — a preserved body — but not a viable biological specimen. Once done, the preservation is final, and the pet remains permanently inert.

‍

Cremation and burial: respectful closure

These options remain the most popular:

• Cremation offers simplicity and allows owners to keep ashes in urns, scatter them in special places, or wear them in keepsake jewelry.
• Burial, whether at home or in a pet cemetery, provides a physical resting place.

These approaches emphasize closure and tribute, not preservation for future potential.

‍

What science adds to the picture

Recent decades have brought a revolutionary option into focus: cryopreservation.

Unlike other methods, cryopreservation aims to preserve the biological structure of your pet — especially the brain — with the goal of protecting memory, identity, and function.

It’s not about display. It’s about preserving the possibility of future revival.

‍

What is pet cryopreservation?

Pet cryopreservation involves using extremely low temperatures to halt all biological processes in your pet's body. The goal of pet cryopreservation is to preserve pets with the hope that future advancements in technology may enable their revival and the treatment of their original cause of death.

‍

What cryopreservation can offer

✓ Structural preservation
Connectome-level preservation (the brain’s web of neural connections) is possible, keeping the patterns that may encode your pet’s personality and memories.

✓ Scientific grounding
Cryopreservation builds on decades of cryobiology used in embryo storage, organ transplantation, and regenerative research.

✓ Ethical care
At Tomorrow.bio, pet preservation is done only after legal death, with full respect for the animal’s dignity and for the hopes of the owner.

‍

What cryopreservation can’t (yet) do

✗ Revival is not currently possible
Cryonics is a long-term bet on medical progress. No pet — or person — has been revived yet. The science is promising but speculative.

✗ It’s not reversible today
Once your pet is vitrified, they remain in storage until such a time (if any) that revival becomes a reality.

✗ It’s not right for everyone
Some people prefer closure over hope. Some want a visible memorial, not a scientific procedure. Cryonics isn’t about guarantees — it’s about preserving possibility.

How to plan ahead

If you're considering cryopreservation:

• Start early — ideally while your pet is still alive.
• Use our pet calculator to get an estimate and understand the steps.
• Inform loved ones so everyone respects the choice when the time comes.

‍

What preservation means to you

Ultimately, the choice comes down to meaning.

• Do you want to remember your pet visually, symbolically, or biologically?
• Are you drawn to tradition, or open to emerging technologies?
• What aligns best with your values, grief process, and long-term hopes?

There’s no one right way to say goodbye — only the way that makes the most sense to your heart.
