Cairo is now one of the last 3 out of 8 of my oldest standing rescue’s I had from the same rescue situation over 2 years ago, she was also 1 of only 2 double-rex’s of the 8. At the estimated age of about 32 months she is in immaculate health and has always maintained immaculate health throughout her entire life here (no tumours, lumps, abscesses, no RI’s, no eye issues, no internal issues, no neurological issues, always maintained perfect body mass.) Cairo has never required veterinary treatment in her whole life. At her age she is continuing to show absolutely no signs of deterioration or any degenerating body condition at all. You hear a lot of negative press surround double-rex’s and their “poor health”, but honestly from all the rat related health issues I’ve witnessed in rats that have anything to do with the genetic makeup, she’s the best example of a double-rex I’ve seen, and before anyone blamed “good breeding, she is obviously from a top quality breeder”, wrong. Cairo is a feeder rescue from an overrun BYB who who absolutely not on a mission to breed healthy rats. 66% of the group I rescued from him have all passed now, some from deteriorating health, some from veterinary intervention, but this “unlikely” healthy double-rex in her shining golden years is one of the healthiest old ladies I’ve ever had the pleasure of owning. Learning more about genetics and the DR gene is helping establish a better understanding of the variety but a lot of information found is now borderline outdated and not a reliable source to base knowledge on anymore. I’m interested to do a lot more digging around with DR’s, definitely very fascinating and I love my princess wrinkle bum Cairo!
