Wayne Silver Prince is just beautiful! They grow up to 3 or 4 years old and they will slow down after that. I think it is true the bigger the more gentle. Thats why they are called Gentle Giants. My Shadow didn't grow at first but that was because he was a stray and wasn't properly cared for. When he got some TL C and all the food and water he wanted he started growing and he is still growing and filling out. he is three years old now! I dealy love him! Who ever dumped him on my doorstep, lost out on a very nice kitty. if they didn't think anymore of him than that, They sure didn't deserve him! I'm thankful I found him.
