One of my neighbours has a kitten they are giving away and I'm so tempted to have him as I'm worried he will end up in a bad home. I have two year and a half old girls and I want to be sure I'm not just jumping into it. Do three cats work ok? Is it hugely more expensive for food etc. My girls are like a couple of kittens still playing and running round the house like nutters will they take to him Ok?
