Hello, I have two new hairless siamese dumbo females. They're lovely and we adore them, but since they're both hairless, it's very hard to tell them apart. The only way we can really tell is by looking closely at the markings on their tail. I'm trying to teach them their names so it's important to keep them straight. My husband wondered if there was a way to somehow mark them with something natural, like maybe a bit of food dye, on their tails. Does that sound crazy? Have you ever marked one of your rats?
