This has not been a good week! My little girl, Snowflake, is walking very strangely. She'll stretch out completely flat -- but stay stretched and drag the back half of her body. I don't even know how to describe it, I've never seen anything like it. She manages to get around, but she almost looks deformed. Her legs and posture just don't look right. She was completely fine last night during playtime, so I'm very worried. Has anyone seen anything like this? I don't know whether this is an emergency or not, but it just started so suddenly! I've had rats with injured legs/feet, and this is nothing like that. She doesn't seem in pain..
