Why is my cat chewing with front teeth??

I noticed that my cat eats and leaves a mess of crums of his food everywhere, i tought i was ok but then i noticed that he is chewing hard food with his lil front teeth. Why is he doing that??? I gave him a treat(hard) and he starts to bite with small front teeth, he doesnt even eat it, i dunno why. does he have tooth ache? hes just 9 months old. anyone knows???

Take your cat to the vet. It is not normal for them to eat that way. To me, that suggests a broken tooth somewhere in the back of the mouth, and he's avoiding chewing because it hurts. Broken teeth are EXTREMELY painful, especially if there is an exposed pulp cavity (the place where the root lives). Get the cat to the vet ASAP.
Reply:he probably has a toothache i would take him into the vet to get it checked out... cats dont tell you when their teeth hurt so its good to see warning signs like that.
Reply:Please take him to a vet right away. He probably has dental/gum disease problems as the other person said. You do not want to fool around with this, because if his mouth pain increases, he may stop eating all together, which leads quickly to very serious health problems for cats!
Reply:I agree, he probably does have a bad tooth. You need to take him to the Vet, ASAP !!! Don't wait until it gets worse.
