Norwegian forest cat, the pet of Vikings www.iizcat.com/posts.php ?postid=3567/Some-facts-ab out-the-Norwegian-forest-c at-the-pet-of-Vikings
The video in the article - at the end are a few pictures/links. One leads to a video explaining the difference between the maine coon & norwegian forest cat. I could see several similarities.
I've had 3 coons. A friend had several NFC. They are similar. It could be possible that viking cats breed with north american cats to form the breed. Have wondered what genetic tests show.
Had internet/pc woes tonight, but it worked out before I retired. Sorry for the long pause.
