Thanks everyone.
He's not thin AT ALL, he's actually got quite the little gut going on. If you were familiar with the Modern Siamese breed you would know that they are a very lean cat.
I wish you guys could all meet him in person, pictures don't do him justice at all.
LOL yah he's all legs and his tail is soooooo long and skinny. I'm constantly petting my cats from their head right down to their tail and when I do it to my girls now it feels like they have stubby little tails
