​The amazing, colour-changing kitten!

Hi, I’m Bruce the cat! I was found on a footpath when I was one day old. Back then I was as small and grey as a mouse.
 
A few weeks later, when I opened my eyes, they were blue.
 
When I got bigger, I developed dark points on my paws and face. Lots of people thought I was Siamese!
 
But then something strange happened.
 
I got darker…
 
And darker…
 
And darker! My fluffy grey fur turned sleek and black.
 
And then my eyes changed from blue to green.
 
I’m magic!
 
But really, there’s a scientific explanation behind my amazing changing colour.
 
Kittens are born with blue eyes, but most don’t stay that way. At about four weeks old a kitten’s eyes start to change colour, and they don’t settle into their grown-up colour for about three months. (It might be a bit later for me, because I’m a bit of a late developer.)
 
But what about my coat? Why did I change colour from grey to black?

This not only had me stumped, but also my mum, my dad and my vet! I still haven’t been able to find any scientific information about this, but thanks to the internet I am pretty sure I had a condition known as ‘fever coat’.
 
According to the internet, if the mother cat is sick or stressed during pregnancy, her kittens can be born with fever coat. Fever coat makes the fur appear lighter than it should be for the first weeks or months of a kitten's life. In my case, I changed colour when I shed my kitten coat.  
 
So there you have it – the answer to the mystery behind my amazing changing colour! If you have any information about fever coat please let me know in the comments. ​
