That was pretty hard to listen to. Glad he shared his story though. From the sound of it I'm not sure if quarantine would've even helped him.
It seems like if you're going to quarantine an animal, you REALLY have to make sure that you keep everything separate to the point of possibly interacting with quarantined animal on a different day than the rest of your collection. Depending on your living situation, that might be hard to pull off.
Honestly, I haven't taken quarantining seriously in the past but this video definitely changed my mind.
