My cat coughs, pees blood, and misses litter box. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

My cat has had a bad cough for 8 months. He coughs every time you pick him up. Recently he has started peeing on the bed and when he does go in his litter box we have noticed blood in his urine. Our vet out him on medication for the cough but it didn't help. Any guesses or advice on what this could be and to get him to stoping peeing outside the litter box would be appreciated!

Poor kiity. THis is a very long time to have a cough. Permanent changes to his lungs are highly likely at this point, so the cough may never go away compleely, but we can at least do things to improve it. The first step here is to find out the underlying cause for the cough. Hiro needs to have x-rays taken of his chest to get a proper diagnosis. Once we know the underlying cause for the cough, then we can know what specific treatment he needs. Coughing can be caused by numerous things including: bronchitis, heart disease, fungal disease, or even a lung parasite. I would also recommen baseline bloodwork so that we can get an overall health assessment of Hiro and also look for further clues to solidify the diagnosis. He is likely peeing outside the litterbox now b/c he is stressed. Cats especially get stress cystitis (inflammation of the bladder). Other possible causes would be urinary crystals. He needs a urinalysis to find out for sure here so that he can start treatment for this also. I do hope that Hiro's cough improves soon! Best wishes moving forwrd. Take care!
