My cat Squeakers is 8 years old and has had 3 round black marks on her lips since she was about 6 months old. They've gotten a tiny bit larger as the years have passed. They bother her only very slightly when she eats. Please don't tell me they're cancer. She's had them 7 years.
Also, the roof of her mouth is black. What's going on? She's playful, loving, and none of these things seem to bother her. I can't afford a vet as I'm on a very limited fixed income. She eats a lot, drinks plenty of water, has normal bowel movements and urine. Help!
