Cats urine is normally very concentrated, so a dark orange color could be OK. With a UTI, they tend to urinate more frequently, urinate outside the box and sometimes strain to urinate. If you see him doing this, then he needs to see the vet. If anything else is concerning, then it's best to bring him to the vet and they can easily test the urine and examine Mookie for any other problems.

    Any change in elimination behavior, especially when coupled with a change n odor and color of the urine, could indicate a urinary tract infection. I recommend getting Link seen by your vet as soon as possible for an exam and urinalysis. Dark orange could mean the urine is highly concentrated or there could be blood present.

    Drinking excessively can have various causes, diabetes, kidney failure, slty food, etc. The only way to diagnose kidney failure is via a blood test. Dark reddish orange urine can be caused by a urinary tract infection, bladder stones or other irritants damaging the lining of the bladder or a kidney infection. I suggest you take Buddy to a veterinarian for an exam and a blood test. That should find the reason for the problem.
