|Hi Charlie, I can tell you how to fix this, I have show cats, but sometimes I find, that telling someone the truth, even tho its what they asked for, can sometimes get me in trouble, so I have to be very careful, how I word it, which, I don't do anymore, LOL, its just too time consuming, and makes my head hurt, LOL.
So, I will approach this another way.
We all know what happens, when parents don't disaplin children, or teach them manners and responsibility. Its part of shaping them into well adjusted and responsible adults.
You mentioned the possibility of children. What are your plans to teach the child manners and responsibility?
Think of your 7 month old kitten, as a young child, he must be taught "now" what his boundries are, same as a child is taught, he must be taught manners "now" and he must be taught, his parents are the head of the pride, and he must yeild to you both.
Mine are very very well behaved. They didn't come from the breeder like that, they were taught and trained, starting as 8 week old kittens.
I can tell you, if you don't correct this right now, very minor and very easily corrected issue, its just going to get worse. If you asked Jackson Galaxy, he would tell you the truth, but, he ain't gonna get in trouble for it, LOL.
I also know all about Siberians, they are rare and very expensive, and you went thru a very lenghthy and very carefull screening process by the breeder. They felt this was a good match, or you wouldn't have the kitten.
The breeder is there to help you, with any problem, they want you to contact them, if you have an issue, they want the kitten to have a good home and be taught manners.
I also know, that neutering him, was in your contract. Some let the kitten go, and require proof of neutering, before they give you registration papers. I know how Siberian breeders are, most, will have him neutered and all his shots, before he goes to his new home, usually at 12 weeks, some at 16 weeks, I get to take mine home at 8 weeks, because I am very well known on the circuit, and very well known for having very well behaved kittens on the circuit.
Best to contact your breeder, they will be very happy to help you with this, and they aren't going to get in trouble, for telling you the truth, LOL.
How you do this, is no different, than a momma kitty, disaplining her kittens, its the exact same principal. Best of luck, whatever you decide to do, but ya gotta do it "now".
