My cat has very little amount of fresh red blood in his stool for every defecation. The stool is hard on the beginning of the defecation and and justlittle bit watery on the very last part with a little blood on it and the poop is brown in color. He is not having a diarrhea, constipation, vomiting, and he is not straining he only poops once a day. He is very active, has a very good appetite and doesn't seem to be lethargic. The vet also palpated him and he said he is okay. They perfomed a fecalysis and haven't found anything. They also haven't found anything on blood test. Could this be dietary? BTW, he is eating a heavy meal each meal like 3/4 of 3 oz can per meal of wet canned food he is eating 4 to 5 times or 1/2 can of 3 oz can each meal if I am feeding him 6 times a day. He is always hungry and has a big appetite. Could this be just overeating? Or is there something else? Btw he is 8 years old
