Do Kittens Change Color As They Grow?

I have a newborn litter of Norwegian Forest kittens and was wondering if they lighten or darken in color as they grow? Thank you.

Pigment production is usually more sparse in kittens than in adults, and most often any change of colour will be to darken rather than lighten. There's quite a difference between my Sonic at 3 months and Sonic now at over a year old - he's blue (the changes can be most noticeable in dilutes, if you exclude colourpoints) and has gone from a mid-grey to a dark steel blue as he's got his beautiful adult coat through.

Yes, the color may take quite some time to fully develop.

Also the rufous colour in tabby (all patterns) cats can take a while to come in. I don't know how much rufous is usually in Norwegian Forest cat tabbies. It's the red or rust red undertone in the coat.

My bengal has changed from having an almost yellow coat with her tabby markings to now at 2 years old having a rich auburn base coat.

Her face as a kitten and then now. You can see a big colour difference.

Color usually darkens on kittens as the adult coat comes in. In some breeds it may appear to lighten - like the Korat and Russian Blue as more silver tipping comes in

I'd not taken into account silver tipping but generally speaking unless you're expecting that, the coat darkens as they get older.

Siggav - I adore the colour of Nikita, I am not a huge fan of tabbies unless they are silver, or brown with deep rufousing like yours - gorgeous rich colour there
