I don't get why rats are ever be considered vile and disgusting creatures. They groom themselves constantly, and when tamed, they are the most loving things in the world. They are fun to be around, and very intelligent.
Please please use humane methods to keep these little ones put your home. They may be little but they suffer and feel pain and fear as much as we do . Traps glues and poisons are not an option when plug ins and fresh cab botanical repellants work so we!
