Gerbils on the run!

This is all a huge mess! I'm in trouble for something I didn't do, again! So, in the beginning, I let my brother (Tyler) hold one of my pet gerbils , Sirius. I know, it was a thought-less thing to do! Well basically, after he'd put him away, he left the cage open...

They escaped.

I got the blame.

So now I have two gerbils lose in my house. I've got no clue where they are. For all I know, they could be in my neighbours house. Or lost for ever. Now I'm starting to panic! Its been 2 hours and still no sign. Where are they?!
