Does your ship have a Pet?

Did you leave your cargo door open too long while unloading and now have a bat-equivalent predator flying around your ship?

Did an Opossum-like creature crawl into a hatchway while you were making repairs?

Did your ship's cat let you know that there was a 7 foot tall creature behind you?
