From your description of his hyper behavior and his coat markings, there is obviously occicat in his heritage. These are bred to be closer to cats in the wild.
The other types of cats with the more hyper personalities are cats of Eastern heritage such as Abyssinians, Siamese, etc. But they typically are smaller in size and slimmer in body structure.
The other part of his heritage is what’s known as “cobby” type of cats. They typically have larger bodies, thicker fur, but far more placid dispositions. Examples would be Norwegian Forest Cats, Maine Coons and others associated with Northern climes (as opposed to the slimmer Asian and African type cats like the Occicat and Siamese types)
So it looks like he’s a pretty good balance between the two basic types. In other words, a very hardy and healthy mutt with gorgeous coat markings.
The only thing you may want to watch out for, medically speaking, is a higher incidence of HCM among Maine Coons and Weegies. This is linked to a dominant gene so potentially hereditary.
I had a gorgeous Callie who had the size, coat type and personality suggestive of this heritage and died at only 11 yrs old from a stroke. Very shocking and unexpected to me.
In subsequent research, I found out more about the genertic connection. An ultrasound can detect the early signs of the enlarged right chamber of the heart if your vet deems it wise. But, hopefully with your guy, the Eastern part of his heritage prevails and he lives a long happy 20+ year life.
I certainly dont intend to alarm you needlessly but, it’s just something to be aware of. He is such a gorgeous boy.
