anastasia: Ewwww, ewwww, ewwww, no Do they all have a bad prostrate, or urinary tract infection, or what? - LOL - I've never been told that by a Vet & trust me, I've taken just about every pet to one from snake to bunny and babies. I've had rabbits as pets (and they're in the lovely rodent family that has to "poo" like a machine), but one was actually litter-box trained & the other two got to live in the yard (till the neighborhood stray cats called them lunch). You've peeked my curiousity on this one, I've gotta go check it out. I know that male cats that aren't fixed leave urine traces everywhere they go, but I didn't know that rodents did that too.....Thank God I'm a "bleach-freak"
