Allowing cats to roam is an ecological catastrophe, a public health threat, and above all, is an example of animal cruelty. Before I learned my lesson decades ago, I let two very dear four-legged friends meet a bad end because I thought "they could take care of themselves". They could not. I strongly encourage anyone who does this to learn from my example. Keep your cats indoors or in an outdoor cat run.
