It wasn't unexpected, and I'm glad that he didn't just slip away alone in his vivarium for me to find later, but today I'm angry.
Like almost all of our animals, Nutty was rescued. When he was given to us (by another rescue centre) we were told he was brain-damaged - hence "Nutty Norman", which I never actually liked as a name. We didn't know how old he was, just that he was adult when he came to us.
Getting to know him over the first few weeks, I started to doubt if he was brain-damaged or just rather stressed. The shaking he originally had lessened considerably, and although he often held his head to one side, I know several people who do the same, and no-one doubts their mental capacity as a result!
So Nutty and I had several happy years together. I say Nutty and I because - for no reason I was ever able to fathom - Nutty growled at Luc every time he saw him. Until about three months ago.
At the same time that Nutty stopped growling at Luc, I notice the lean of his head was more common, and a greater angle. He also started going round in circles occasionally. A couple of weeks ago, he turned so far round on himself that he actually flipped himself over. His last shed was poor. He's never been any easy feeder, but then last Saturday he had difficulty eating his usual food, but managed something smaller. Then he stopped eating altogether.
There's a genetic flaw in leopard geckos called the Enigma gene. Some animals may carry it without ever exhibiting symptoms, but when they are present, among the most common effects are:
- Neurological or balance disorder;
- "Star gazing";
- Inability to feed itself;
- Circling behaviour, especially when startled;
- "Death rolling" (think of crocodiles);
- Inability to shed without assistance.
So now, taking into account a few other factors as well, I'm pretty sure that the "brain damage" that Nutty had was, in fact, the Enigma gene.
So why should I be angry? Because the Enigma gene is being deliberately bred for financial gain, producing animals that - to a lesser or greater extent - suffer as a result.

When the "Enigma morph" was first bred in 2006 (three years before we were given Nutty) it was considered "exciting" as it introduced new colouration and also less obvious "banding". As a result, entire Enigma lines have been purposely bred, and sometimes crossed with other colour morphs. A number of breeders continue to do this, with any hatchlings exhibiting clear signs of "Enigma Syndrome" being euthanised and the others being sold on or kept for further breeding.
Enigma is a dominant gene.
I can only hope that Nutty didn't suffer too much in his final few months, but had I been aware of this genetic mutation earlier I would probably have taken steps when his condition started to deteriorate at the start of the summer.
