just aftrer christmas there will be loads of cats and kittens due to unwanted gifts, and they keep coming into the shelters for at least 4mths as the cute kitten grow into unwanted cats...

we have had a few cats and the best cat we ever got was 16 weeks old from the RSPCA, as people go into the rspca all the time to look at cats and sit with them so they get real used to people...

its great that you are wanting to get a shelter cat/kitten...

dont be afraid of the older ones as all cute little 6week old kittens will turn into 6mth old cats one day...
