Quick question for those of you who own rats and pigs. A friend has asked me to take care of her two pet rats while she's on vacation next month. I would be keeping them in a separate room away from any of our pigs. I just want to be sure our pigs will be safe, and cannot contract any infections or diseases from the rats. I want to help her out, but of course our pigs are our 100% priority. Any advice would be greatly appreciated. Thank you!!
