I believe those are livebirds, which are usually sold as a pair because of the mated bond. I've always wanted a pair, but my cats are scared enough of our dove, I can't traumatize them with 2 more birds.
Yeah they put the cat in scardy cat. Sad thing is one is a 20lb behemoth. He's also literally s ared of his own (admittedly large) shadow. But the dove in 20 years old and sees them as mere children to be tolerated only so much.
