Sounds like it has a furball, you may need to get a vet to give you a prescription to help the cat be able to get rid /expel the furball. Www.petalia.com.au/Templates/StoryTemplate_Process.cfm?specie=Cat...

 This does sound like fur balls and instead of going to the vet and spending a lot of money I found that a little Vaseline on the end of the nose where the cat can lick it off takes care of the problem nicely.

 Probably a fur ball. Put vasiline on the top of its front paws, he will lick it and it will coat the esophagus and the fur ball will come up easier.
