CRYOSLEEP
FOR OUR FURRY FRIENDS
At the end of their natural lives, we offer cryoSLEEP for pets as an alternative to burial or cremation, giving them a chance at life in the future.
Cryosleep
Cryopets develops whole-body cryopreservation protocols to pause biological time for pets when there are no other options.

Stabilization
Our procedure begins only after clinical death of the pet once they've reached the end of their natural lives. In ideal cases, this is directly following euthanasia, avoiding ischemic damage and allowing for lab-quality cryopreservation. To begin the process, we administer multiple medications to aid in the cryopreservation procedure and prevent clotting. We place the pet in an ice-water mixture to start to cool down the body.

Perfusion
Next we transfer the pet to the surgical area and begin perfusing the brain and body with cryoprotectants, which are a sort of medical-grade anti-freeze. This is done via aortic cannulation using a perfusion circuit. As we continue to cool the pet down, higher concentrations of cryoprotectants are perfused until the concentration is high enough for vitrification, ensuring we form a glass-like substance instead of ice crystals. This is vital to avoid the damage that ice formation causes to cells.

Slow Cooldown
While it's important to quickly cool the body down initially, at lower temperatures we use slow cooling to prevent thermal stress, mitigating fractures. Depending on the size of the pet, this can take a number of days. This is accomplished in our slow-cooldown box, a large device that injects liquid nitrogen into an enclosed chamber over time, gradually dropping the temperature down to −196 °C.

After slow cooling is completed, pets are transferred out of the slow-cooldown box and safely secured in cryogenic dewars, immersing them in liquid nitrogen. These dewars are periodically topped-off with liquid nitrogen to maintain their temperature, and pets are kept there for the long-term until revival. This means pets will maintain their temperature even if there is a power outage.
