I am usually a more worried person, if the cat is not normal one day, I basically do not say that the first time to find out, it is not long, I found that my big cat sid one day is very sleepy, in fact, cats sleep quite normal, but he slept, when my husband and I came home, he did not come out to greet me, aroused my suspicion, I went to my mouth and saw drooling accompanied by a foul smell. However, I only had a cat for half a year and had no relevant experience. I immediately consulted a doctor and was told that it might be stomatitis.I was lucky enough to buy Mutoral when my cat had her first stomatitis and she was treated quickly and made a significant difference.
