Hello! I have a blue domestic longhair. He resembles a Nebelung but he is not pure bred. Do longhairs keep getting fluffier as they age up till a certain point? I have seen pictures of his father (also a blue domestic long hair and his mom resembles a turkish angora but also not pure bred) and he was much fluffier than my kitty. Also, the father was much bigger in size which leads me to my second question. At what age do cats stop growing? I have seen that it is around 2 yrs but I feel like my kitty is still far from a being big sized kitty and he is 1 yr and 9 months old. Thank you for your help!
