Stressed pets.

On our latest #prongcast, Prong2 told me that rats get stressed. I’ve never been a pet person (why would you invite an animal into your house?)¬†so I didn’t know if he was having me on. Do you/did you have a pet that suffered from stress and how did this stress manifest itself? Let me know via the comments button or @anunknowncomic¬†
Cheers
