I have had 2 cats develop a disease within weeks of dental procedures.One was a 9 year old who had just a cleaning & within a month began eating voraciously, yet losing weight-hyperthyroidism & passed within 6 months. Just recently my 13yr old developed some abscesses, so extractions had to happen. Fine the first week, now has kidney disease. What's with this dental procedures seemingly triggering something the cat had no signs of before. All my Vet could say that it happens. Nobody seems to have a clue. I'm tired of losing beloved family members over something that's supposed to be "no big deal" and needed for health? I'm at a loss, both cats wouldn't respond to any treatments or medications either. *sigh*
