Elvis is adorable!

I used to call Charlee "spike" because when she was a kitten her hair was spiky and crazy looking. Here she is doing her dance, first day home with me.

She grew into a long haired cat

 

Elvis color looks to me to be Silver Tabby & White in most photos, but if there's a warm brown hair coming in especially around the head, then he could be a Brown Tabby Somewhat difficult to see the barring on his sides whether it's like tiger stripes or a round bull's eye.....the tiger stripe is called Mackeral, and the bull's eye Classic or just Tabby. So his color and pattern could be Silver Mackeral Tabby & White. The uneven shorter coat on sides and longer in back is similar to a Maine Coon Cat whose coat is uneven with it shorter over shoulders and longer in belly and britches and with a long fluffy tail.. It takes almost a year for a kitten's long coat to develop. If there is any Maine Coon Cat blood in him he will be a big cat.....long in body and males can weigh up to 20 lbs. Of course, he may or may not be purebred, as that can only be determined by having the proper registration paper work, and pedigree from a registered Maine Coon breeder.. At the moment he is regarded as a "Domestic Long Hair". He has a very sweet and friendly facial expression and I'm sure you'll have a lot of fun with him. All the best!
