I think the guessing on all white cats is almost as difficult as on the blackies.
Also, being a kitten he hasnt grown yet into his adult proportions. For example these biggish ears - when he has grown up, they will perhaps be just slightly bigger than average, we cant know that yet. Also, his shorthaired kitten-fuzziness CAN still turn into long hair. I have seen such happen, it was like a changeling.
For now, its just to ponder on all the known shorthaired all white cats, to try and find a look alike.
He has blue/grey eyes I'm not good at that.. his mother was a little fluffy not very long hair .. yip he can hear properly .. very sharp ears..lol. I have to be carfull at the middle of the night if I want to pee.. but he must come after me..
