Why does my kitten have bad breath and drool when he purrs?
The area that I think you are concerned about is the lighter colored and thicker area on the bottom lip. That is a normal part of the bottom lip that is thicker than the surrounding area because it is where the upper canine tooth hits the lip. He should have a similar thickened area on the other side, but the coloration may be different. Cats with Orion's coloration can be varying pigment along their lips and gums, so some areas will be pink while others will be dark. That is not a reason for concern. At 7 months of age, Orion should have all his adult teeth. If you are noticing bad breath, it would be worth having your veterinarian examine his mouth to make sure he doesn't have any retained baby teeth that are causing a problem. Finally, it is very common that cats will drool when they purr, but most cats do it from kittens. If Orion has just started drooling when he purrs and has a change to his purr, it would be worth having your vet palpate his throat, lymph nodes and larynx to make sure everything feels normal.
Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
