Was strongly considering Rats, Gretel must be very calm if she's just chilling on your bed.
I'm saying 8.5/10.
This is the only photo I can find, sorry about the feet.
A foot for scale maybe? Not a problem at all. Gives you some scale, Gerbils are much smaller I've had two Gerbils in one hand before.
I have lots of sewer survey videos featuring rats. Given that I got these while at work, is that too professional?
I guess if it was you doing the sewer survey then sure go for it! Just didn't want this to turn into a "look at this cool picture/video I found on the internet " kind of thread.
