we had a Maine Coon cat looked just like yours.
Gads, I do believe you're right, Farmerman, I've accidentally adopted a mostly-Maine-Coon cat!
Checked this breed out (via Internet, of course) and Happy Kitten matches on most fronts, except his ears are smaller and not as pouffy as breed standards.
Really, I was curious about Happy's "mostly" breed in case of health problems in later years.
I've had great luck with our "mix"-cats-and-dogs, all strays. They seem very healthy and long-lived.
Our oldest is a Pit Bull dog mix, at 14 yrs old, "Poo." Wuv her!
Thanks for the tip about Mr. Waddy-Fwuff.
