Thank you for your email. I suggest you use the Traumeel drops to reduce the inflammation and then support this with 1 tsp of apple cider vinegar in his/her food and maybe also a seaweed supplement for cats.

Then most veterinary practises sell toothbrushes for cats and dogs. You may also need to gently brush the gums and teeth to keep them clearn.

Finally i would look into feeding raw food or at least some raw bones for them to chew on. There is a great deal of information on the net about feeding raw food for dogs and cats and the many advantages – and this is certainly worth looking into and reading up on.
