Tooth infection help
Hi, I need recommendations for this situation. My cat underwent a tooth extraction on Wednesday the 12th (60h ago). Today I noticed that the area looks bad, she's a difficult cat and doesn't like getting handled, so these pictures are the best I could take.
The problem is, the clinic where she got surgery is closed on weekends, and we don't know if she got any antibiotics injected during the operation. After discharge I was only prescribed Loxicom (Meloxicam) to give at home, so I suspect she already has a long-lasting antibiotic, but I can't be sure.
I called two emergency vets because I wanted to take her in, but they told me they can't prescribe another antibiotic because we don't know which one she already has (it's probably Convenia, which is a cephalosporin, but it could be another one, and antibiotics can interact negatively with each other, which could harm her kidneys and liver).
I'm super worried because I know tooth infections can be dangerous, and I think it has gotten very bad in 2 days.
Any recommendations on what to do? I feel my hands are tied, and I don't know if we can wait two more days. In addition, in my country, there's a law that regulates antibiotic use and veterinarians can only prescribe something that is not broad-spectrum with an antibiogram and culture.
Thank you.
TLDR: infection 60h after tooth extraction, clinic is closed, emergency vets can't prescribe antibiotics without knowing if she got any already and which one
Additional info: she's eating and is not lethargic. She also purrs and leans onto me when I pet her. From outside the lip isn't swollen.
