How do you tell if your chip is cinnamon? My male Bob has ginger fur around his back, its the only way I can tell him apart from my female.
To help you Ste and so i don't thread jack Barry's topic, i've made this new topic where members can post their Cinnamon pictures

Hi Ste, first i'll tell you about my experiences of owning them. First the mum was my very first Cinnamon i bought her for £60 in 2001 and she was in the shop with a boy Cinnamon, i didn't buy him. Two weeks later she had babies - four i didn't know she was pregnant so was a surprise. At first i didn't know if they were Cinnamon like her, they looked exactly like Agouti pinkies when born. When they started getting their fur they were looking lighter than Agouti, didn't have the ginger look though. I still wasn't sure until they had all their fur, they all were lighter than their mum. Sadly two died the surviving two Ginger and Hazel (in pics above) survived and they gradually got darker once adult and eventually looked the same colour as mum Sandie but it took awhile before the ginger colour came through. My Bailey i bought of Dayle C last March looked similar to Hazel and Ginger at 8 weeks old when i bought him at eight weeks old and as he neared adult he developed darker ginger colouring of the centre stripes and tail and ginger rump. But he always did have a gingery look when i saw him at Dayle's.
A Cinnamon looks like an Agouti with the same amount of stripes ect but the body colour is light brown or orange. The five black stripes of an Agouti are a chestnut brown. The brown stripes surrounding the centre stripe of an Agouti become orange. The white stripes of an Agouti stay white. The belly is white. The tail becomes orange or light brown. The rump near the tail is often a ginger colour. The eyes are the same colour as Agouti but they have white claws and often white whiskers. The face stripes are chestnut brown and white with white ring around eye like Agouti. The top white face stripe goes from nose to ear. The bottom face stripe eye to ear. The same applies with the chestnut brown stripes. The back of the ears are white. The colour is recessive just like Dilute White. They appear to be quite rare compared to the Agouti and the Dilute White.
Genetics of the Cinnamon (same as Dilute White)
The Cinnamon is a recessive colour like Dilute White and for what i call pure-bred Cinnamon's you need two Cinnamon parents. Two Cinnamon parents will breed true meaning they will not have Agouti in litter. An Agouti from one Cinnamon parent and Agouti parent are known as 'Cinnamon Carriers', they have the Agouti colouring but carry the recessive ' Cinnamon gene' which means in future they can have Cinnamon babies themselves if bred to another Carrier or a pure-breed Cinnamon. I do find genetics quite complicated but i will try to explain below:
Cinnamon female and Cinnamon male - all babies Cinnamon
Cinnamon female and Cinnamon Carrier male - some babies Cinnamon, rest Agouti
Cinnamon male and Cinnamon Carrier female - some babies Cinnamon, rest Agouti
Cinnamon Carrier male and Cinnamon Carrier female - some babies Cinnamon, rest Agouti.
If your boy has a ginger back end he could be a Cinnamon, would have to see pics to tell. I have posted some more pics of Bailey below so you can see better and some of Ginger and Abigail (Agouti) together
