Pet cell preservation: a new way to help pet parents through grief.

One routine skin biopsy, taken at your clinic, preserves your patient’s living cells in liquid nitrogen. For deeply attached families, it keeps hope open at the moment everything else is closing. Most simply keep the cells as a living memory of their pet.

No equipment, no training, no setup cost for your practice.

Why it helps

Families ask about cloning. What they are really looking for is hope.

Almost every family who contacts us starts with a question about cloning. Only about 7% go through with it. The others keep the cells frozen, as a living memory of their pet and a possibility they are not ready to give up. What they want, in the days around the loss, is not to have to close the door for good.

Time to grieve

Nothing irreversible has to be decided in the week of the loss. The choice can wait years, or never be made.

Hope kept open

Many families describe it as an investment in hope: circumstances change, prices may fall, and the possibility stays with them.

Something they can do

At a moment of complete helplessness, a concrete step they can take for their animal, while there is still time.

What pet parents tell us

“Today was probably one of the worst days of my life. This is the only thing that made it better.”

Catalina, United States

“Thank you for your kind support at my worst moment of 2025.”

Gabor, Spain

“Thank you so much for your kindness, responsiveness and genuine involvement in helping us. It means more to us than I can express.”

Irina, Russia

“I thank you a thousand times for your help in our distress, which lets us hope to find again a part of the ball of fur we love so much.”

Serge and Lidiya, France

“I trust you are doing a great job, I am just naturally curious and nervous as Tyson was very dear to me. Thank you very much for your time. I really appreciate it.”

Nestor, Greece

“Thanks for the update and for your great professionalism throughout the process. I am really happy that everything went smoothly.”

Antonio, Italy

When and how to mention it

You know which clients struggle most with the loss of one particular animal: the ones who ask whether anything else can be done. Cell preservation is for them, not for every family.

The right moment

  • End-of-life planning for an aging or terminally ill pet
  • Quality-of-life consultations, before euthanasia is scheduled
  • Within a few days after death, if the body has been refrigerated

What to say

“Some families choose to preserve their pet’s living cells. It is a way to keep a part of them, and to keep options open for later. Would you like some information?”

That is all. If they are interested, we take it from there, including every question about cloning.

Your role: inform, not sell

Most families have never heard of cell preservation, and those who find it on their own often find it too late. Your role is only to mention that it exists, to the clients for whom it is relevant.

The science

What is preserved, and how

From a small skin biopsy, our laboratory grows dermal fibroblasts, verifies their quality and freezes several vials in liquid nitrogen at −320 °F (−196 °C). At that temperature the cells remain alive and viable indefinitely.

Why living cells

DNA alone, from hair or a swab, cannot be used for anything beyond testing. Living fibroblasts keep every future option open, including cloning by somatic cell nuclear transfer, should the family ever choose it.

About cloning

Cloning produces a genetic twin of the pet, not the same individual: memory and personality are not inherited. It is carried out by a specialist partner, only if the family decides, often years later. We answer all cloning questions directly, so your clinic never has to.

How it works

Five steps, three of them at your clinic

A standard veterinary procedure, with a written protocol we provide.

1

Identify

Devoted owners of aging or terminally ill pets, showing anticipatory grief or difficulty with end-of-life decisions.

2

Inform

Let them know cell preservation exists. We supply the client materials.

3

Biopsy

Standard skin biopsy, placed in a sterile tube with sterile saline. Details below.

4

Ship

Express courier, arranged by the clinic or the client. Refrigerated at 35 to 39 °F, never frozen.

5

We take over

Cell culture, quality control, cryopreservation, storage and all client communication.

Time window

Post-mortem, the biopsy should be taken within roughly 5 days, with the body refrigerated at 35 to 39 °F (2 to 4 °C) and never frozen. Warmer conditions shorten this window sharply. For terminally ill patients, an ante-mortem biopsy gives the best cell quality.

For your team

The biopsy, in detail

The only procedure required from your practice. The aim is living dermal tissue, collected as cleanly as possible and kept cold, never frozen.

Procedure

  • Site. The inner thigh is ideal. Local anesthesia or light sedation at your discretion when the animal is alive.
  • Preparation. Clip the hair completely and disinfect with 70% ethanol only. Avoid povidone-iodine and chlorhexidine: residues are toxic to the cells, while ethanol evaporates completely. Let the skin air-dry for about 30 seconds.
  • Sample size. Either a 5/8 to 3/4 inch punch (1.5 to 2 cm), or an elliptical excision of about 3/4 × 3/8 inch (2 × 1 cm), which is often easier to close. Full thickness, including the dermis.
  • Container. A sterile tube filled with sterile 0.9% saline. Close the site as usual.
  • Before shipping. Keep the tube refrigerated at about 39 °F (4 °C), away from light. Never freeze.

Pricing and partnership

Clear pricing for the family, a fair fee for your practice

Families pay Bimini Pet directly for preservation. Partner practices receive a referral fee for every preserved sample, and can bill the biopsy to the family as they would any procedure.

Common questions

What veterinarians ask us

Is this appropriate for all my clients?
No, and it should not be offered that way. It is meant for the small group of highly attached pet parents who struggle most with loss. For most families it would misread the moment.
Isn’t this really about cloning?
It is how most families first hear about us, and we are open about it. In practice, only a small minority go on to clone. The others keep the cells as a living memory and a possibility for the future. Many do not clone simply because they cannot afford it today, and see preservation as a way to keep that door open.
What does cloning cost, if a family asks?
Around $50,000 for a dog or cat, through our specialist partner. It is always a separate decision, made directly with us, never at your clinic.
What are the ethical considerations?
Cell preservation itself is closely comparable to human fertility preservation: living cells are stored, nothing more. Cloning raises separate questions, which families explore with us only if and when they consider it.
Does it really help pet parents deal with grief?
Over the past four years we have worked with more than 100 pet parents in deep emotional distress, and they truly needed help. Cell preservation gave them a way to ease their pain and opened the door to a form of hope they desperately needed. We receive constant positive feedback from our clients, right after the process and years later.
Where are the laboratories?
We have laboratories in both the United States and Europe, so there is no international shipping and no customs paperwork for you or your client. Samples usually travel overnight in the United States, and in two to three days in Europe.

Who is behind Bimini Pet

Dr François-Xavier Pellay, PhD

Dr François-Xavier Pellay is a research scientist who has spent more than twenty years on why cells age and what can be done about it. He has discovered new molecules, developed methods to restore function in aging cells, and today leads Bimini Biotech, where that research continues in AFI+, an autologous fibroblast therapy. Fibroblasts, the cells preserved here, are the cell type he has worked with longest.

Bimini Pet came out of the limits of that work. Aging science is moving, but not fast enough for the animal in front of you today. Preserving living cells is what can be done now, while the rest catches up.

He founded the service four years ago and has spoken with more than a hundred families since, most of them at the point in a pet's life where you meet them.
