I have two adult cats who have had been having soft stool/minor diarrhea since day one in my home. It doesn't seem to bother them, both of them are chubby (one being 14 lbs and the other one 16 lbs) and very playful. They are 2 years old and I asked their previous owner they tend to have soft stools ( the previous owner feed them dry food). The thing is that their stool easily stick to their rears ( they are short hair) and not only their butts stinks but also they stains where they sit.. I am feeding them my homemade raw diet for almost 1 year now. Any suggestion?
