My cat, Pretty Kitty, is the oldest cat we have. I'm not sure how old because she kind of just took up with us a few years ago. A year or two ago, she developed really, terrible bad breath that did not want to go away. A few months ago, she got really sick. My vet put her on an antibiotic, which, thankfully, made her better. The weird thing is, since she finished her medicine, her bad breath is completely gone! I originally thought that her breath problem was due to her age. Now, I'm not so sure. What do you think?
