Introducing iggys

[Strutter769]

I have an adult (10yr old) female iguana and considering also rescuing a 4' male iggy. What precautions do I need to take when introducing/housing them together? (Possibly free-roam for both)

Thanks!

Separate rooms for at least 30 days possibly longer and vet check the new one after two weeks with a stool sample
