I loved this product when I got it in the mail, I mean, they come in pairs! The white cotton is breathable and durable. Everything you'd want in underpants. I've been looking for these for a long time.  These underpants come with all the necessary holes pre-sewn to accomodate 4 legs and a tail. It was tough to get them on Mittens at first but soon with a few staples and some duct tape, he's doing fine. No more unsightly furry male cat genitalia for upstanding citizens to have to be affronted by. Thanks, Handerpants!
