Hello! So, recently, my family took in two female guinea pigs from a local woman who was giving them away. They're super sweet, and I'm in love Anyway, when the woman gave them to us she didn't include any sort of carrier. I would like to purchase a carrier for whenever we need to transport them (for vet visits and emergencies). How large would a carrier for two adult female guinea pigs need to be? Will (broken link removed) carrier work? Thank you in advance!
