My senior cat is drooling thick sticky saliva. Is it a health concern?

Pet's info: Cat | Mixed Breed | Male | neutered | 16 years and 10 months old

Hi. My old cat (at my dad's) is getting on a bit but I have just visited after 3 months away and he has deteriorated gradually to the state where he now dribbles. The saliva is thick and sticky. The black is something he has been in and us hard and crispy on his fur so sadly we have had to shave partly. He has lost teeth through age and now has a blended diet. Is the drooling something to be concerned about or should we just continue to make his twilight years as comfortable as possible?

Even with no teeth the drooling is abnormal. I would be concerned that he has an infection or stomatitis of the mouth or possibly kidney disease causing him to be uremic- a build up of toxins in the blood that can cause ulcers and other problems. I would recommend getting him to a vet for evaluation and possible medications to help keep his twilight years comfortable.
