🐈 PKD (polycystic kidney disease) in cats
An inherited disease in Persians and related breeds; found by DNA test or ultrasound.
What is it?
PKD is an inherited disease that forms cysts in the kidneys, which grow with age and can lead to kidney failure. It is common in Persians, Exotics and breeds crossed with them, and one affected parent is enough to pass it on.
Signs
- Often no signs at first.
- Later: more thirst and urination, weight loss, poor appetite, vomiting.
How does it spread?
Not contagious; inherited. A positive cat can pass it to about half of its kittens.
Prevention
- DNA test (PKD1) or kidney ultrasound before breeding.
- Do not breed a positive cat.
- Regular kidney checks for older cats.
🚨 When to call the vet at once
A cat drinking and urinating a lot and losing weight, or vomiting and not eating.
