The only reason I said persian is #1 for the long coat and #2 I dont hear of pure white maine coon cats usually.
I really only wanted to know what the heck the 2 combined would look like, being they are so different. I always thought the fur would be long and whitish with spots, like a longhaired dalmation but for a cat.
I dont know about genetics so this must sound stupid, but if you google there are some people with persian/bengal mixes, if the persian was all white is a mystery to me there was no photo.
I saw it on Craigslist so I thought mabye someone had photos.
Spotted Persian, something like what I imaged if they crossed.
