Tamaki at about 9 weeks
I actually saved a kitten from being killed by a horrible woman that lets her cats breed uncontrollably. I named him Tamaki from a Japanese anime show. Tamaki hasn't grown very much from 6 weeks to 4 months. The reason why I know this is because I acquired another kitten for the same reasons and named her Luna. She was three weeks younger than Tamkai and she has already surpassed him in weight and height!
I took him to the vet worried he had a disease and he simply said that Tamkai won't be as big as most cats. I love his small size. He is my baby!
