Poor Jinx! This could be a few different things like a tooth root abscess, an abscess from a bite wound, or a benign or cancerous growth. Since it is growing so rapidly, I would strongly recommend to have your vet look at it soon. Your vet will be able to do an aspirate of the mass to see whether it needs to be surgically removed or if medication may help it go down. I hope this helps and he starts to feel better soon!

A sudden, fast growing lump/swelling on the cheek of the cat is likely to be an abscess, basically a pocket full of pus. At that location a dental abscess (form a problematic tooth) is possible but it can also be as a result of a trauma (most commonly fights). Either way the cat need to be checked by a vet, the mouth should be examined closely and the abscess need to be treated. The cat may need dental procedure, antibiotics or abscess drainage.

This may be a cat bite abscess or a sialocele (salivary gland cyst) or a swollen lymph node or tumor. You should make an appointment with your veterinarian for an exam, as a sialocele, while initially painless, can quickly become painful and often the salivary ducts are obstructed. A cat bite abscess needs to be addressed as well and a swollen lymph node can be a pointer to some inflammatory process in the body.
