Was out fencing today and as I neared a patch of bush I noticed what looked like a skunk. The 22 came out and as I got the critter into my scope I realized I was looking at a large black and white cat not a skunk.
Now I know a lot of people are going to freak out but here's how I see it. A cat living out in the wild all on its own is feral and therefore a pest that can have quite an impact on things like grouse and if left unchecked can cause quite a lot of issues.
I did not dispatch this particular feline as I knew its origins were from the neighbors about a mile away. Thinking about it afterwards lead me to the question.
How far away from civilisation does a cat have to be before it's considered a pest?
