for the last 2 holidays ive een on, we've taken my new kitten seafa. we got her the day ebfore a holiday! anyway, our two old cats Kyte and monkee used to just be shut in the kitchen, the room with the cat flap and the neighbour with cats used to come and feed them. they were fine and monkee used to put her ears flat to show us she was glad when we got home. we didnt really worry about them much, as they didnt stray. they just did what the normally did but slept in the kitchen. they were outdoor/indoor cats,. cats are really safe in our neighbourhood. theres only been 1 road accident in about 5 or 6 or 7 years, and apart from that, theres just territorial disputes by neighbours cats (on OUR property) and it our cats were female and they didnt get involved, they were too smart!!
