For thoughs of you that don't know my male rat started loosing weight and detirerating. He lives by his onesy in a 10 gallon tank, which I figured out to be a problem, he was depressed! I started interacting with him way more than I had before, and he is now a happy rat! I also added vanilla extract to his water, he didn't like that at all, and I noticed he was hardly drinking. Changed the water back, and he is drinking normaly now! He has gotten some of his weight back. Thanks for the help to everyone! The females are up to size as well! Babies!
