Yeah I hear you, I've been through that too but not this way, so I get why you don't want to chance it. Can you get a Feral barn cat? My home was abandoned for 2 years before I bought it and had a big rat problem. I put a dent in the problem with poison but then to ensure it didnt happen again I adopted Feral barn cats. It's been 9years with zero rat issues, really works.We live in the country, so our dog and cat go outside freely. I'd have no way to know for sure that they can't get to a dead rat that's been poisoned. We had a dog die 2 years ago that got in to a neighbors farm poison. We had to put her down and it was devistating.
