I used to have a little white bunny with Himalayan style markings only they were grey and much softer. His little grey points would change colour and shape with every moult :lol: normally his nose and ears would change the most. Sometimes he would have just a dark smudge on the end of his nose and sometimes it would be much much paler but cover half of his face :lol:
Once he moulted while we were on holiday an he was almost completely white when we came to pick him up from the boarders :shock: it wasn't until we had had him home a day and he was settled and being 'him' again that we were sure that we had been given the same bunny back!!! :shock::lol:
