When my 18 yr. cat first began drooling when she slept I just figured it was old age.
However, not that long after it became obvious that she had difficulty chewing and she was drooling when awake. I figured it was most likely an infected tooth and took her right to the vet. He was looking all over at her teeth and gums but all the teeth looked fine. Finally he checked under her tongue (not easy to do with a cat) and discovered the sorce of the problem.
There was a lump under her tongue. It didn’t look that large it was clearly the origin. It really wasn’t possible to tell if it was malignant or not without surgery.
So I opted for that hoping it could be removed. Unfortunately, he called to tell me that it was so far involved below the surface that he would have to amputate most of the tongue.
I realized that was no option for a food loving cat like her. He also didn’t think that was a viable idea as it would only give her 2–6 extra months since the tumor would just grow back.
But what I learned is that drooling is not normal and always indicates a problem of some sort. It’s def not just an old age problem so it’s good that you’re promptly taking him to the vet.
Hopefully, your little guy just has an abcessed tooth that needs pulling. I’m wishing the best for you.
Let us know what happens.
