People should get their bloody cats spayed/ neutered and then the RSPCA would not be over run with kittens.
Oh and people should also learn that kittens are not 'ready' at 6 weeks old. 6 week old kittens are not socialised and much more likely to end up in the RSPCA and the likes.
*rant over* Good luck in finding a home for your cat.
Ohhhhhhhhhhhhh! Jer-e-my Cor-byn
