Eventually, this will stop...
Bob went back to the vet this morning. Late last night, we had urination outside the box, obsessive licking of the backside (ie, bald), and blood on the floor = suspected urinary tract problem. Possibility of a bone shard having caused ripping in the bowel, however, and the blood was seeping from there, and mixing with urine leakage for whatever reason. (Pain, stress, UTI...) We're hoping it's a UTI. The fact that she wouldn't clean herself (or let us do it) after her *ahem* issues issues is the suspected cause, if it is an infection.
On antibiotics for the next week.
