Miserable Vinnie, on a scale of zero-to-ten.
0- Mouse feels no pain or anguish. Normal demeanor.
1- Maybe some itching from flea bath, but nothing unusual.
2- More itching.
3- Again, more itching. In places mouse can't get to.
4- Some pain. Will most likely hide in order to appear macho and perfectly fine.
5- Some activities impaired. Fellow mice will notice change in demeanor.
6- Half of all activities impaired. Only a retarded wombat would not notice demeanor.
