These are pajamas with a built in diaper alternative for older kids. Per the company, they are capable of absorbing 3 pees a night. They are perfect for bedwetting and for transitioning out of pull-ups. We have both dogs and cats. Items are washed prior to shipping. These are a tied dyed color, with swirls of blue, blue/green and a faint purple. I could not find this color still on the website.
