Very unique domain that is both generic and brandable, pet food/services/retail is obvious but also adult industry specific. IMO its worth an easy x,xxx right now but to the right buyer could be worth a whole lot more especially if they are going to brand it, the branding process can cost many millions making the actual cost of your domain somewhat irrelevant. Only thing that lets it down is the "s" on the end, I notice that kitty is parked so you might want to join together and market both names together, the singular is worth more than yours though.
