I recently got two new ratties so that my boy Myszka could have some new cagemates. The babies both seem very healthy and happy, yet one of them keeps making this long squeak noise. It’s not particularly loud or anything, the only thing I can equate it to is like a puppy trying to howl just much quieter. I couldn’t find anything online so wanted to ask around and see if anyone knows what this odd behavior could be? I know it could be a sign of sickness so I’m gonna try taking them to the vet soon, but also wanted to get others opinions too. Thanks!
