This is my first rat to do it like this. And shes not even of size to be bred yet. Shes a hold back from new blood source. With her gone itll be a set back on the new blood.

If this is a inner ear problem caused from URI then i wont risk anything, so thats why shes alone in her own setup with her own food and bottles.
