Our Miss BooBoo Kitty had a UTI that was resistant to the usual antibiotics. Then the vet sent out a urine culture and Boo had e. coli!! As a nurse, I kinda freaked out a bit, because I am familar with little old ladies getting a UTI from e.coli because they wiped the wrong way. I never got an answer on how cats can get e. coli!!! Boo was so fastidious in her litter box habits, but what a surprise when she peed BRIGHT RED blood right in front of me. Boo was not a cat of subtle behaviour!!! I hope Luna will be OK!!!
