Thanks for reaching out about your cat's swelling under the jaw. I completely understand why you're concerned. There are several possibilities for this type of swelling. It could be an abscess, often resulting from a bite or injury that has become infected. Another possibility is lymph node enlargement due to an infection or inflammation. More rarely, it could be related to dental issues or salivary gland problems.
At home, you can gently monitor the area for any openings, discharge, or increasing redness. You might apply a warm, damp compress to the area for a few minutes a couple of times a day; this can sometimes bring comfort if it's an abscess starting to form. Be careful to watch for pain or discomfort while doing this.
Keep an eye out for any changes in your cat's eating, drinking, behavior, or any other symptoms like lethargy or fever. If the swelling is increasing, if you notice your cat is in pain, or if there’s an evident wound, these are signs that it might be more serious and need prompt attention.
I recommend booking a video consult with us at Dial A Vet so we can assess it more closely and guide you on the best next steps for your feline friend.
