Abandoned singles can name a cockroach after their ex-partner and feed it to Texas zoo animals for Valentine's Day.
Participation in this curious fundraiser is possible worldwide, said the San Antonio Zoo on Sunday evening (local time) on Twitter.
Depending on the amount of the donation, those interested can choose a cockroach or a rodent to be fed on the zoo's website.
There is also a veggie option: For five dollars, a head of lettuce or cabbage can also be symbolically named after the ex-girlfriend or ex-boyfriend.
Anyone who wants to let their former partners know about the revenge action can download a greeting card, it said.
For 150 dollars, the equivalent of around 138 euros, there is also the option of receiving a video of the feeding – including a personalized greeting.
The cockroaches and rodents are already dead at the time of feeding and are included in the zoo's feeding schedule regardless of the fundraiser.
Valentine's Day is on February 14th.
Valentine is considered the patron saint of lovers.
Last year, the campaign received more than 8,000 donations from the United States and more than 30 other countries around the world, zoo director Cyle Perez told CNN.
So far, the most commonly used names have been "Zach," "Ray," and "Adam."
According to the zoo, the names "Jacob" and "Sarah" topped the list last year.
