We were in a similar situation a few weeks ago, our cat of 21 had to be put down and we lasted a couple of days before going to look for another kitten.
The wife had said I could have a British Blue ever since we watched "Cats & Dogs", although that is a Russian Blue I think.
But when it came to it she said she didn't like the dark blue color
So we went to see some amber british shorthair kittens which were cute but didn't grab me.
The next day we went to see some more british shorthair kittens, some of which were blue/white, some blue, some tortoiseshell, etc.
Later that day we went to see a lilac shorthair, born from a blue tortoiseshell mum and a blue dad, who was a big bruiser of a cat.
the lilac looks blue sometimes, and brown at others, depending on the background, so is a good compromise (!)
Ty is chubby enough around the face to have that same sort of look that a british blue has - which I was keen on as everytime I look at a British Blue I can't help smiling as they look slightly 'comical'.
He is now 20 weeks and we have had him for only 4 weeks.
He is fantastic fun with a great personality - I got home late from work yesterday and the wife was complaining that he had been waiting for me, looking out of the window.
I went upstairs to change and he came up and jumped on the bed ready for a play - I use a laser to get to to run repeatedly around the bed to the point where he stops and pants - not sure if that is good or not...
He goes really hyper a couple of times a day - normally just as we are trying to go to sleep, but maybe that will reduce when his nads are cut off in a couple of weeks
We got him at 16 weeks, which is slightly longer than normal as most breeders seem to let them go at 12/13 weeks.
Having seen the other kittens I would say that it is not worth going to see them until they are close to that 12 weeks as they have less 'personality' evident from which to judge whether they are right for you.
But having said that, Ty was pretty nervous of us when we met him, although he was calm and slept in the box on my wifes lap as we brought him home a few hours later, but he isn't nervous now and was at home almost immediately. But we could see his confidence, whereas we couldn't really with the younger kittens.
We are feeding him on Natural Instinct cat food :
and also some Honeys, which is 95% meat, compared to whiskers at something like 4%.
His toilet is much better and his coat is softer than the softest thing you can think of, so it was definitely worth it.
