Is he supposed to be this big?!

       
(Across these pictures he's about 2 or 3 years. I apologize for the fact that there are pieces of me in almost all the pictures, lol.)

Alright. So I've had Ezekial for about four years now and I have always wondered what kind of cat he is! It's my hope that someone will be able to help me answer the question because I'm stumped. I originally thought he was some kind of Siamese Mix (and I suppose he still could be?) with his very pale blue eyes and (what I initially thought were) lynx point markings, but as he got older I became a lot less certain!

I adopted my baby cat from the county animal shelter I was working at during the time, because he was slotted for euthanasia and I couldn't stand to see the beautiful little boy get put down. He came in as a (more scared than actually feral) feral stray at about 3-4 months old and looked VERY different than he is now!

  
(These are pictures of him days after I brought him home)

Since I got him, none of the vets (previous to my current one) were much help either! As a kitten Zeke had an absurdly long tail, so I figured if nothing else he was probably going to be a tall cat! However, the first time I brought him to the vet for his initial just-came-home-from-the-shelter check up I asked the vet about this and they said no. That he shouldn't get too big. [Insert Eyeroll Here]

He's now 23 pounds and a VERY BIG cat! When he lays on me, which he does often because he is my cuddly, teddy bear kitty, he is the full length of my torso and that's without him even stretching out. He is also loves to talk and is usually at the door to greet me when I get home from work so he can tell me ALL about his day and what trouble he and his older brother (Siamese Mix in the last picture above) Hezekiah, have gotten into!

I'm as curious to know what breed he is because of his weight as anything else. Whenever I bring him to the vet  the tech always casually mentions to me how obese he is and that there is a high risk of he could develop diabetes. This really concerns me as his momma, but at the same time, I don't personally believe that he's drastically overweight. He's far more active than his older brother and regularly climbs into the tall cat tree I keep outside on the lanai for him to sleep in the top perch. He has no trouble getting around and isn't restricted in his movement at all, but maybe I just don't want to see it if there actually is a problem? :\

Anyway, I'd appreciate the help! Thanks guys!

Now, as we see on the pics as kitten, he is very apparent an lynx point.   You say its not that apparent on his pics as adult, but its because they  points do darken up with age.  Especially the tabby-lynxes, whom get tabby coloration on only on the face-masque, but usually also on the whole body...  the only is, on half his body he is sort of a spotted tabby - not that common, but on the other half, he is sooner a broken mackerel.  So we must settle on the broken mackerel tabby pattern...

Yeah, lynx point still.

He is naturally a big guy.  May perhaps have some Maine Coon or Norwegian behind, a granddad perhaps.   Although none of these breeds are known to be points, but with mixes everything is possible...

He probably isnt much obese, but have your eyes open on it - its never good...

The color is prob blue.
