Hi Just as a matter of interest, I will relay this information, if it saves another another cat from suffering. I lost an Elderly cat to Mouth cancer in September having visited the Vets approx seven times in as many months they failed to diagnose mouth cancer and said after three visits to three vets and a major complaint to the owner of the practice at the same practice that she had Gingivitis which had caused bad teeth the advised that she needed to have five teeth extracted this they did. But when she still had difficulty eating they did tests for Kidneys etc, etc, etc still they did not diagnose mouth cancer until the final day of her 17 year life when I put down her breakfast and she tried to eat but could not open her mouth I took her for her final journey and the Vet could not open her mouth they kept her overnight to do this under anethestic I had at that point told them I suspected she had mouth Cancer they rang me the next day at work and told me that the Cancer was so far advanced it had eaten the muscle in her Jaw and they let her go whilst she was still sleeping. I work in a Dental Surgery and one of the dentists told me that if Mouth Cancer is suspected you do not extract teeth as this gives the Cancer somewhere to go and causes it too spread. That poor animal must have suffered so much because I took the word of a professional instead of listening to my gut intincts. This is a lesson I have learned.
