Saladmander respawn/breed

Hello, guys. I'd like to make a saladmander spot in my megabase, so I saw in a video few months ago someone saying that he telelocated a saladmander to his base and few day later she replicated without him knowing how. The dst wiki have nothing about it, so I came to you to ask if there is a way to replicate my saladmander. btw thanks for the answers.
