Recently, Dave has discovered a rat hole outside and, with a cats unwavering patience, lies in wait for the rats to emerge. And his patience has paid off a few times. But, twice now he has eaten his kills and I wondered if that could be harmful for him. (By the way, he is well fed at home

I don't think anyone has put poison down and quite frankly I'm glad. I'd sooner the rats were killed by my cat. It's more natural somehow. But when it all boils down to it, Dave's welfare is more important to me than the rats. So.....what can I do? I've blocked the hole as best I can, but I'm willing to bet there are others.
If I report it, won't the vermin control put poison down? I'm in a quandary so any suggestions would be so helpful.
