Trying to get Fluffy to open wide for a thorough tooth brushing can be even more stressful for her than it is for you. So, unless your cat's been having her choppers brushed since she was a mere kitten, it's going to most likely be a struggle. Fresh Breath and Dental Toothpaste enables you to freshen and clean your cat's mouth and teeth without the use of a toothbrush. Simply add the paste to her food or apply it directly to her gums with your finger. The manufacturer says it contains natural anti-bacterial agents, including eucalyptus and cinnamon, as well as several natural breath-freshening ingredients, such as parsley seed oil.
