my guy (sauce 2) became a blacklight pet when i shot her with the zapper, and now idk wut to do with her, but someone else might want her. so iz there a way to sell her or something to someone that wantz her?

no, and I believe it's against the rules to try to sell or auction a pet. You should read the rules here: https://subeta.net/help/faq.php and scroll down to where it says

Please be aware that you CANNOT trade or sell pets. If you are caught trying to trade or sell your pet(s), you risk being warned and/or frozen.

Although those rules are out of date, and pet renames are currently free and they don't need to be unique, I'm pretty sure the rule about selling pets is still valid. If you need verification of this, you can create a ticket to ask staff.

That was a lucky zap! Selling or auctioning pets (or generally exchanging them for items/currency) is against the site rules, but you can adopt her out if you want. Some users who are adopting out pets might ask for applications or a basic description about what the adopting user plans on doing with the pet, so they know it goes to a user who will actually make user of the species/color/etc.

ah oki, thanx for the help
