My kitties are eating about 75% raw now. When I got them from the shelter a few months ago, they both had giardia, URI, and one had worms. After deworming, clavamox, and 3 rounds of meds for the giardia, they continued to have loose, bloody stools. UNTIL I got them on raw. Poops are so much better now!!!! Smaller, firmer, and less frequent, no blood, I am so happy! My question is this: I'm using Nature's Variety because it's available locally to me, it's the most reasonable cost-wise, and so far my kitties love the beef, chicken, and duck. But I'm sort of concerned about the bone content of it-- I don't want them to go too far the other way and get constipated! They love canned pumpkin, what do you think of giving them some regularly to kind of "offset" the effects of the high bone content?
