I have a bit of dilemna. My local charity is desperate for foster carers for pregnant cats (and subsequent kittens). I have a 7 year old neutered female at home. She has shared before with other cats but not for the past 2 and a half years. Is it fair on her and a pregnant cat to be in the same house? would it be too stressfull for foster? would the foster be more prone to aggression if pregnant/ looking after her kittens? I'm currently fostering a kitten but he will hopefully have a home on saturday and i've been able to keep him in kitchen and Molly (our adult cat) in rest of house. Would it be cruel to do this to a grown cat?
