Rabbit going grey?!.....

Got told last night from my brother that one of my bunnies is going grey!..:shock:
Is there any cause to panic over this, he will be 4 years old this coming spring, which i dont think is partically old for a bunster?...
Could it be just his winter coat?, He is naturally a white bunny, with a dark black nose.
Starlite is known for changing some colouring in the summer, his nose goes from black to ginger:shock: but i have never known, or noticed him going grey before....

I'm guessing his coat is coming through a different shade of brown, his nose looks the same colour as Charlie's from your pic and his brown markings vary from a redish/ginger colour to a darker more greyish brown, he also has some dark grey bits that have come through more recently. I wouldn't worry about it.

Silver went grey as she got older,

All round her mouth and a fair bit of her nose went grey


You can just about see the tips of her ears here, they were almost completely grey;
