Jen, I tried to see if I could find out how old BraveHeart is, but I cannot seem to locate the thread with that info. So, how old is he? Our oldest cat, Norton, at 16, was recently found to be anemic. Our vet said it can be a disease of older cats(just like older people). We have Norton on Pet Tabs with Iron(1.25mg/2.5cc), which he gets twice a day. Nortie is scheduled for a repeat CBC on 3/11. If the values do not go up, he will be started on the epogen just like BraveHeart. Luckily, Norton does not have kidney disease. Sorry to yak about my cat, but just thought if BraveHeart was an older gent, that with the kidney disease is why he might be anemic.
