A mouse is a tiny rodent, and the animal can be a pet or a pest depending on the exact situation. Mouse quotes show that these animals may be small but they are feared by many and featured in a wide range of cartoons. A mouse can be a health hazard if the rodent has any diseases or illnesses that can be passed along to humans but their cute appearance causes many to fall in love with this type of animal. If you have a mouse in your home then you have options. You can leave the animal alone and coexist with it, you can trap the rodent in a humane way and release it far from your residence, or you can use a trap which kills the animal and then the body is disposed of.
