Gill - I wouldnt worry about your renewal, I am paying the same for Molly as I was last year, despite having put in a £200 claim, and it seems that the cats on the old excesses are being honoured, as she is still down as a £50 excess. I did ring AXA and they said that males are more expensive to insure (I assume cos of the cost of blockages, which females rarely get, and poss more risk of fighting).
It has only changed in the past couple of weeks though, as my friend just insured her 13yo female for about £13 - she only lives round the corner, so should be in the same postcode band. Must ask her what her excess is though.
Will do a new post about the new arrival at some point (prob when he gets here, as I have no pics till then, and it would be pointless without them!!)
