Smells too much like menthol and makes the cats resist.
We have been brushing the teeth of our 5 cats for many years, ever since they were very young, and we've never had them resist before, but with this tooth gel, they do. Normally, we can brush their teeth calmly and easily, but not anymore. It's probably because it smells/tastes too much like menthol. The bottle says that one drop is enough, even for brushing. It turns out this is NOT the right tooth gel/toothpaste for our cats.
