I had 2 cats from the RSPCA about 2 months ago, they are lovely, they didnt know each other but are sort of tolerating one another (M&F) the male cat is about 6 months old and will be at the female all the time wanting to play, she tolerates it up to a point then has a scream at him, most of the time this puts a stop to it, if not I throw him out to give her some peace. Yesterday, she was let out after being inside with him all day, a bit of an error normally I seperate them and put one out in the day and one out at night just to be on the safe side, anyway, back to my story, she was let out at 8pm and is still not home, when do I put posters up and assume she is lost, is this normal, or has she ran away from home as she is fed up of the kitten? These are my first cats I have always had dogs before.
