I took Riley my 9 month old to the emergency vet this morning cause he was pooping blood mixed with poo (it was caught around his fur near his bum which is how I noticed it). I informed them when they asked about diet that I fed kibble (kirklands) and canned food at night (whatever flavor I happen to buy). He checked his glands said they were normal and then proceeded to tell me after I told him since switching all the cats to canned food only 1 cat has normal hard stools (Riley never has normal stools). He told me it was constipation or hairballs. Told me to switch him to Hills and gave me laxatone and told me not to give it if he has the runs only when hes constipated....he never has a solid stool so how could he ever get constipated. I want your opinions, he hasnt pooped since (that ive noticed), hes his normal active self and is still eating and drinking. Could this be the food causing it maybe I should take him off canned and keep him on just kibble?
