We have critters in the house. Mice and something larger. Steven trapped a rat in late November. A nice, healthy, country rat. The problem with rats, country or not, is that they come in packs. We suspect there is at least one more. We hear it at night sometimes. Nothing in the trap this morning. I think my next dog with be a Rat Terrier or a Jack Russel or a Dachsund. Something that is bred to hunt and kill vermin. Standard Poodles are retrievers. They do get very aroused, none the less, when the critter is skittering around.
