I have 13 indoor cats and for 6 weeks 4 or 5 of them have had diarrhea so bad that they are leaking everywhere they go. Until a wk ago i fed them 9 Lives or Kit & Kaboodle Indoor Dry food mixed with any kind of canned food 2X a day & b4 this it controlled the diarrhea. Last wk i switched them to Friskees Farm Favs Dry food wth real chicken & reg Friskees canned food hoping that would stop it but it seems to b worse. I am on a very limited budget but need some food that will help. Any suggestions
