I got the cytology report from the vet today on Cleo's mouth scab.
Consistent with what we thought. Some bacteria only. Nothing more serious and the bacteria load was not very high.
The vet continues to think she bit something and it scabbed and never completely healed right. Some sort of trauma.
She said from now on, most applications of the chlorhexidine oral treatment can be put on her lips and she will move it around with her tongue on her own. No need to stress her out more.
Also, as of yesterday, she is done with the metacam.
Further, if the scab comes back, and quickly, the vet can prescribe and oral antibiotic for her. However, we are both hoping that this the oral rinse will be enough.
I've been spoiling Cleo and she's been getting hornworms and wax worms to make sure there is something in her stomach with the medicine. I'll go back to her mealworms mostly diet today.
