I've seen pictures of hedgehogs outside. I'm assuming people are using playpens when they do. Obviously not at this time of the year, but possibly during the spring when it's in the mid 70s or low 80s for the temperature. Would you need to be worried about fleas though?
That's another question I have as well. I have dogs that get flea treatment, but sometimes they get in. Is this something I need to think about with my hedgehog?
