Of course. I live on remote farmland and I have a half-acre garden with no neighbours. I've lived here for 34 years. Yes I have a cat. Yes I've had other cats during my stay here. I'm beyond reproach. I know that there are many urban cat owners but I can't speak for them. My pussycat stays within fifty yards of my house. That's because of my level of control. Whatever my cat gets up to is as nothing compared to the devastation caused by loose dogs on our local nature reserve.
