I rescued a cat of the RSPCA and when I went to pick her up they said there had been some blood in her stool, but it had cleared up. They'd run some tests and there was nothing to worry about.

So I got her home and took her off her medicated diet (slowly) and fed her the recomended dry food from the RSPCA (James well beloved adult) but it made the blood come back again. So I went to my local vet and picked up some Royal canin sensitivity SC31 which stopped any blood in her stool. After feeding her that course I gradually re-introduced the james well beloved, but have noticed the bleeding has returned.

Im going to pick up some royal canin one my way home tonight, but I was hoping someone could recommend me a good alternative to the james well beloved which is similar in constituency to the royal canin..... Im reluctant to continue feeding her the royal canin sc31 as it is very expensive (i think its counted as a medical diet). Im also hoping for a food with no additives etc.

cheers for your help in advance (sorry I havent lurked on the boards for a bit before posting, but Im quite keen to get her sorted out ASAP)
