A. In male cats (especially those under the age of 8) urinary tract infections are actually extremely rare, and this is more likely a sign of feline lower urinary tract disease (often abbreviated FLUTD). His inability to urinate is a very concerning sign, and indicates that he may be experiencing a blockage in his urethra. If this is what's happening, it has the potential to become a life-threatening emergency. I do not recommend that you wait for veterinary care - I recommend that you visit an emergency vet tonight, so that he can be assessed for a potential obstruction and treated.
