Leah Kateb is doing her big one for animals! You may know her as the breakout star from season six of Love Island USA, and now, she’s using her platform to speak up for a cause close to her heart: adoption. Just in time for Valentine’s Day, Kateb and her adopted dog Blue are ‘coupling up’ with PETA to urge everyone to dump breeders and ‘swipe right’ on compassion.

In PETA’s sweet new video, Kateb shares how she has fostered hundreds—yes, hundreds—of dogs, including her forever companion, Blue. “I actually started fostering (Blue) when she was just six weeks old,” Kateb says. “I fell so in love with her, I just had to adopt her.”

A passionate advocate for adoption and a regular animal shelter volunteer, Kateb reminds folks that buying animals supports a cruel industry that contributes to the companion-animal overpopulation crisis. “There’s literally no excuse for anyone to be buying a dog,” she says.
