I live overseas were vet care is very limited. My 2 yr old cat has a severe mouth infection. It appears to be a ulcer or sore in the back of mouth Have tried local vet for over a yr without success. Any suggestions? TMHi TM, Try flushing out the cats mouth with 1 tsp salt mixed into a cup of water to soothe and help heal the ulcers. A viral problem may be the cause-be sure your cat is vaccinated for the basics and have your cat blood tested for Feline Leukemia and FIV to be sure he or she is not infected. PAAWS is a great supplement to boost your cats internal immunty and would be very helpful for your cat.
If I can help further please let me know.
