Tina, I would get Amore to the vet asap.  This is probably a urinary tract
infection or bladder infection, so she'll need to be put on antibiotics.
They will do a culture of her urine there and decide the best course of
treatment.
 
On the off-chance they don't find an infection, have them study her urine
for crystals indicating possible bladder stones.  This is more rare but can
happen all the same.
 
Also, if she's not defecating this could be indicative of an intestinal
blockage.  She may be trying to poop out whatever's there and all that comes
out is urine.
 
I wouldn't wait much longer -- Amore doesn't sound like she's in pain now
but could be very quickly.
 
Good luck.
 
Amy & Dave (and their gaggle of giggling ferrets)
RIP Ian and Elektra
