It is not really bad, but I have noticed that it doesnt smell that great. I just switched from her kitten to cat food last week.

Yes. A change in food can cause GI upset. Also depending on the food it might be a little more odorous. you might want to take a moment and read up on feline nutrition at http://www. catinfo. org a website run by a vet who actually studied feline nutrition. Most vets do not.
