Apparently Blood

Is that the same as Blood+? Cuz I remember watching a few episodes of that. It was a little gory, but not nearly that bad. I just remember that there were these monsters referred to as mice for some reason (despite not resembling mice at all), and then the vehicles full of equipment used to track them down were called cats. And then there was one time a mouse got loose, and his name was Jerry, so they tracked him down with a cat named Tom... 

Oh! And then there was one character that I thought looked kind of like Sebastian Michealis. 

And that's all I remember about Blood+.
