We had a crate when we got Cow for his own safety. He was 2 pounds and very tiny. I was afraid that if he was free around the house someone could step on him in the dark. We also left him in it when we had to go out so he would not get into trouble. Cow is now almost 4 years old and he goes into his crate at night or when we go out. We never close the door anymore but he feels safe in it. Also, Cow tends to be a little aggressive when friends come in until he gets used to them. I keep him in the crate when we have the exterminator, the electric company or cable here. Don't want him to get us in trouble if he attacks someone.
