My shorthair cat is grey with white pointing. He was out in the rain today, and also licking his leg some. We noticed that with the fur slicked, he has a very tight (*much* tighter than the typical tabby striping) pronounced zebra pattern of light grey and dark grey on his leg. And presumably everywhere, although this is the only place we have ever seen it. Super weird, never seen anything like this, and we have had cat for 3 years! Is this common?
