Bruce the Kitten made quite a splash last year in social media when people became fascinated by his coat changing from grey to black as he grew older. While the transition had a magical quality, it is actually attributed to something called “fever coat.”
According to messybeast.com, “Fever coat usually means that the mother had an infection while pregnant or that she was stressed or on medication (the last condition can happen if the owner doesn’t realise their cat is pregnant). The kittens have the so called “fever coat” when born, but it fades and by the time they are about 6-8 months it has gone completely. Fever coat is means the pigments haven’t been properly deposited in the fur so it can appear silvery-grey, cream or reddish. In extreme cases, black smoke kittens have been born with what appears to be Siamese colouration – a creamy coloured body with black extremities.”
