Question
My cat has bad breath, e.g. when yawning. Is that normal or is it a sign that he might have dental or digestive issues? Apart from that I haven't noticed anything out of the ordinary.
His menu mainly consists of "Royal Canin Indoor" dry food and cat grass.
Answer
The short answer to your question is yes, there is a possibility that extremely bad breath in a cat is a sign of either dental issues (such as tooth decay or gingivitis or worse) or of more general sickness that is not otherwise visible.
Alternately, you may be hyper-sensitive to the smell of that particular brand of cat food once ingested. One way to find out is to change brands, but just move to it slowly so that the cat acclimatizes to it. Cats are not keen on changes there.
The thing is, I think it's worthwhile assessing your cat a bit. If he doesn't seem appropriately active, perhaps more lethargic than usual, or sensitive to certain forms of petting, then getting a check up might be good. You can also inspect his teeth (they're a little fussy about that, but don't let him win) and see if things look okay. Yellow discoloration isn't a big problem, look for signs of really reddish and inflamed gums, loose teeth, blackening, etc. Any sign of that kind of thing and you should get him into the vet.
If all is well medically, try a new food. It may be that you're just not going to find a cat's breath that tolerable... I'm not a fan either. :)
