Where the issue begins?

So feral cats are different from stray cats, what's the issue? The issue begins with feral cats that are result of abandoned strays who have not been neutered/spayed. According to the Humane Society of the United States, cats can become pregnant as young as 4-5 months of age. A female cat who is able to become pregnant can become pregnant as many as two to three times a year. This is extensive considering that a cat can have huge litters up to twelve kittens or more. If these kittens go on to survive, they will be fertile feral cats who are likely to reproduce. It is obvious with these statistics that the amount of feral cats is growing rapidly. You many wonder "okay there is a lot of them, but where is the problem?"
