Well I came home tonight to find one of my White Lipped in the bottom of her cage on her side and she was gone. I know she was fine last night and she has been perfectly healthy. It almost looks like she jumped into the glass and broke her neck. Is this even possible? She was a little rambunctious so it just makes me wonder. I looked her over (once I could bring myself to get her out of the cage) and she looked fine physically except she had turned the bright green instead of the brown that she normally was (that was always strange since my other one is bright green). She was in her own cage because I was waiting for her to get a little bigger before I put her into the cage with my bigger one. Has anybody ever heard of one breaking it's neck or do any of you even think it's possible?
