I have 2 1/2 months old male persian kitten. It is not still dewormed , bought it a month ago , came to know about deworming few days ago . Whenever I feed cat food, changed the cat food too, kitten has blood in its stool and has diarrhea . Whenever i stop feeding cat food, diarrhea is better than before . Is this the problem in dry foods ? I also came to know that diarrhea and blood in stool is also caused by parasites / worms. Someone told me that it is also because of stress, but kittens seems to be fine to me .
