What kind of cat is sprinkles

Wondering what kind of cat sprinkles is. I found him when he was about 2 weeks old. For his 1st couple months he had long black tips on the tops of his ears. They have gone away now and he has tufts of fur that stick out from behind his ears. Hes only 7 months and weighs 15 pounds.... hes not fat at all... just very large. His tail is very bushy. I have also noticed his pupils always seem to be big and round... not the "normal slits". He acts very much like my shihtzus.... he will play fetch until you take his ball away. Hea very smart... any suggestions?

This is when he was younger

Domestic medium hair, tabby with white, or  tabby tuxedo if you so want.

Some ancestry being so big?  We have to choose among the Maine Coon or Sibirian...   If you live in North America, the Maine coon is most probable.

Very sweet!

Thank you for your response!

Sprinkles is gorgeous!

He looks like a mix between a siberian and some kind of domestic longhair. What a sweetheart, give him kisses for me!
