Mairead's weekly series Obsession continues, and this week it's the turn of Dublin man Collie Ennis who is obsessed with creepy crawlies and the "lesser loved" pets of the world.
Collie has always had an interest in wildlife and while working as a security guard in Trinity College, he spent a lot of time in the Zoology Department. His knowledge and passion for these animals lead to him landing a job as a Research Associate there.
Collie has also taken his interest home - his collection includes over 100 tarantulas, scorpions, frogs, salamanders, newts and snakes to name but a few.
When Mairead asked him if there had ever been any escapes, he told her about the time a Giant Train Millipede went missing in his house and showed up in the last place you'd want to find it!
