  • Fusobacterium
  • Propionibacterium

Moreover, the veterinarian will run some laboratory tests, including urinalysis, biochemistry profile, and CBC. In addition, in case the vet has already started to suspect septic arthritis, they’ll order x-rays, which will allow them to look for some changes on the cat’s joints. In case the vet sees abnormal or unusual bone formations, irregular joint spaces, or bone destruction, this may lead them in narrowing the prognosis down, yet the process is not yet done.
