Is there not a neighbour who could pop in and feed her. They do love their own places but will soon settle down if they are away for a while. She will, definitely ignore you for a while but will soon come round. We leave ours in the care of our neighbour who is also a cat lover, for the last two years though our son has been here so he does the deed. They still ignore us for a couple of hours when we return.
Go and have your holiday and enjoy yourself. If you want a house/cat sitter any time on Anglesey (love the place) we are happy to do so.
