Give your pet the chance
they deserve with cryosleep.

What is cryosleep

Cryosleep is an ambulance ride to the future for your pet.

01
Stabilize
After clinical death, we take action. Medications, initial cooling, and cryoprotectant perfusion.
02
Transport
Following field surgery and initial cooling, we bring your pet to our long-term care facility.
03
Cooldown
At the facility, slow cooling gradually lowers temperature toward −196 °C to limit damage.
04
Cryosleep
Pets are secured in cryogenic dewars under liquid nitrogen until future treatment is possible.
05
Revival
When medicine advances far enough, the goal is to restore your pet and reunite you.

The alternatives are burial or cremation.

We offer a chance at life again.

Cryosleep procedure

We offer three procedure options.

Standard Preservation (VM-1)

Our standard protocol using VM-1 cryoprotectant. Balances quality and cost for most families.

Recommended

Advanced Preservation (M22)

Our most advanced protocol using M22 cryoprotectant. Designed for the best possible preservation.

Option

Basic Preservation

Traditional freezing without cryoprotectants. Most commonly used when vitrification is not possible. A lower-cost entry option.

Procedure pricing can be paid over time up until the preservation.

Cryoprotective agent quality

VM-1: proven vitrification protocol; widely used in cryobiology to minimize ice damage and support tissue viability; more affordable than M22.

M22: research-grade formulation; whole mammalian organs have been recovered from cryopreservation using M22-based protocols; best possible quality.

No cryoprotective agent - ice forms during freezing, with greater risk of cellular damage; lower quality preservation.

Long-term care system

Indefinite storage until revival

Built to keep every patient in care for as long as revival takes.

Liquid nitrogen-196°C

SYS.01

No ongoing power dependency

Long-term cryogenic storage does not require continuous electrical power. Liquid nitrogen maintains preservation without relying on the grid.

SYS.02

Funded for long-term care

Families pay for storage once. That fund is managed conservatively so care reserves can stay ahead of inflation over time.

SYS.03

Committed until revival

Patients remain in storage for as long as needed, with continuity of care as the central mission. Our team has pets cryopreserved at Cryopets as well.
