In my humble opinion, these high generation cats are more rare, thus valuable then any other cats.
You might not think so but:
New cattributes are coming all the time, fancy cats also, gen:0 until Nov. 2018.
To breed a high generation costs allot of money and there are only a few in existance atm.
What do you think about my thoughts? I'm maybe the only one hahaha :-)
Have a nice day!!
