People sometimes ask why I don’t do PCR testing before kittens leave my cattery. Let me explain clearly.
PCR (Polymerase Chain Reaction) is a laboratory test that looks for traces of viral or bacterial DNA. Veterinarians often recommend it, but in practice it mostly serves two purposes:
It brings money to the clinic. Each test is an extra bill.
It creates fear. When something shows up, owners start to believe their kitten is “sick” — even if the kitten is perfectly healthy.
The truth is: every living being already carries countless codes inside. Our bodies — and the bodies of animals — are like computers. From birth, the “system” already has all possible programs installed, including those that could lead to illness. But these programs are dormant. A kitten is born perfectly healthy.
What matters is whether those programs stay silent or get triggered. And what triggers them? Stress and fear.
👉 In stressful situations, the immune system can “switch on” certain hidden programs — things that would normally stay dormant. Think of it this way: every living being is like a new computer. When it is born, it already carries a full operating system with many programs inside. Most of them are never opened, never activated.
A kitten may carry the potential code for many things, but it remains healthy as long as those programs stay dormant. Stress, fear, or unnecessary medical interventions can act like a “click” that activates something which otherwise would never appear. Sometimes it’s not even the kitten’s stress but the owner’s anxiety — animals are extremely sensitive to the emotional field around them.
PCR tests can sometimes detect these dormant codes. But instead of bringing peace of mind, they create panic — and that fear itself can become the trigger that makes the kitten actually sick.
Even the act of taking a tiny kitten to a clinic, drawing blood from a vein, can cause such stress that it activates what otherwise would never have surfaced.
The reality is: viruses exist everywhere. We live in a world full of them. But a healthy kitten, raised in a clean home, does not need to be treated as if it is ill.
That’s why I do not do PCR testing on my kittens. I want them to remain strong, stress-free, and truly healthy.
✨ My goal is simple: to raise kittens who stay healthy in your home, without unnecessary fear, without unnecessary tests, and without being turned into “patients” from the very start of their lives.
