They are very good. And tells me what is going on! This is a case of feline acne. Many cats get this--some will only get blackheads while others like Tabasco get worse cases with large white heads that can get infected and cause swelling and lots of pain on the lower jaw.
Sometimes antibiotics are needed in severe cases, as well as steroids to bring down inflammation.
If you want to try treating at home, you can do the following:
Make sure you are not feeding or watering out of plastic bowls (many dermatologists believe the problem is linked to plastic food
bowls)--instead use ceramic, glass or stainless steel.
Clean the area daily with a warm cloth to remove debris.
Apply a triple antibiotic ointment (like neosporin) to severely affected areas.
Use either acne cream or wipes on the area daily until the severe phase is over, then use every few days to keep the area from breaking out.
Most cats with this problem will continue to have some level of problem most of their lives, but it is a manageable problem.
I hope this helps, please let me know if I can answer any other questions!
