_Cozi Sack is made of fleece (interior and exterior). There is a layer of towel and batting to absorb any pee. Fleece
is used as it allows the pee to wick through and it will then be
absorbed by the towels and batting inside, thus keeping your pet dry.
You can use the sack to carry your small animals as it feels more secure
to them or you can use it as a bed.
