If your cat sneezes once or twice, there should be no cause for alarm. However if your cat constantly sneezes, then you should be concerned because your cat could have a health problem.
According to Animal Planet, if cats over the age of three suffer from frequent sneezing and stinky breath, they maybe experiencing tooth trouble, including gum disease and rot. Cats who frequently sneeze and suffer from mucous build up around the nose and eyes may also be battling an infection and should see a vet for antibiotics.
Ironically, if your cat sneezes around you, then maybe your cat is allergic to you. In that case, you may have to move out of your house and sleep in the backyard so your cat can get a good night’s sleep inside the comfort of your own bed.
