A rambunctious reptile caused Regina firefighters to scramble Monday morning, but they soon scaled back their response.

A fire alarm went off after an iguana knocked over a heat lamp, scorching some vinyl flooring, the Regina fire department said.

It happened around 7 a.m. CST at a home in the 900 block of Wallace St., in Regina's Eastview neighbourhood.

When crews arrived, they found there was no fire, just some smoke.

Firefighters left the home about 10 minutes later.

No one was injured, and it's believed the lizard escaped unharmed as well.
