Rats.

I just witnessed a huge mother F'er walk across the back of my garden. My Mrs is freaked out. I'm pretty sure it's just using my garden as a walkway to get to next door, as he keeps racing pigeons. It was about a 100ft from my house. Should I do something, if so what? It would need to be dog/child friendly.

Or am I being a snowflake, should I man up and accept it as part of living in a semi rural area?
