As for getting good health information, try the Rat Guide. It has submissions from longtime keepers, plus veterinary case studies, and is well maintained.
I love your rattie. I think I will always have a few. One died, and they are now halfway through their lives. It is good for me to understand the briefness of life. I feed them too much. Naked rat is old jellow bag now. I would like to do another group portrate a year later. The rat fan club saved the life of one who got mites. He has them again now. The rat report is good.
Cute pets. For some reason when I first read the title of the thread I read "all four ratites in one photo". I thought I was going to see pics of Emu's, Ostriches, Kiwi, and Rhea's. hahahaaha.
