Hi there,
I am sorry Willy is having trouble. I think that the new additions to your family (congrats, by the way) have caused a change in your cats routine that may have stressed him out a little. I think that the inappropriate elimination you are seeing is in fact an infection, because of the obvious blood. Willy will need to see a vet tomorrow and be put on some antibiotics. Urinary tract infections are very, very uncomfortable and usually cats associate this discomfort with the litterbox. They urinate in other places in the hopes that it won't hurt so much. If untreated, urinary tract infections can progress to kidney infections or urinary blockages. These 2 conditions are life threatening and considered to be EMERGENCIES. Please see the following website for more information on UTI.

Because your kitty is male, he is at high risk for urinary blockage. If he tries to urinate and cannot pass any urine at all, he needs to seen an emergency vet IMMEDIATELY, and cannot wait. If he doesn't receive medical attention right away, he will die. If he does fine over night, he will need to see his regular vet in the morning for an exam and urinalysis, and may need antibiotics and pain medicines to start feeling better. He can get very, very sick if this is not treated. Please let me know if I can be of further assistance. If this has been helpful, please hit the green accept button. I hope your handsome man feels better soon!
