How to tell if my cat's lip spots are a bruise or cyanosis problem?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 10 years old | 15 lbs

How can I tell diff btwn bruise or cyanosis? He has 2 spots on lower lip that appeared a week ago. He has history of murmur & current BOPD w/pred & terbutaline daily. He has to be sedated at every vet visit to calm him down for distress. I don’t want to over react so I’d like to be able to tell. No current distress w/breathing & he appears stable. Pics are him sleeping & best I could do. Gums appear normal from what I can tell when I open his mouth.

Hello, it does not look like cyanosis. When pets become cyanotic, they are typically in severe respiratory distress and close to expiring. In patients with heart conditions, this commonly occurs when they are in congestive heart failure. With Leo's respiration rate being normal then I would be less concerned with Leo having cyanosis. Continue to monitor his respirations for any increase in resting respiratory rate. Some cats may develop coughing as well.

Hope this helps and best of luck.
