Hi, I've always had cats and had quite a lot over the years but only ever fed them regular supermarket brands, whatever they will eat on a rotation! They have all lived long lives and been pretty healthy including one almost 20. I'm seeing lots of ads on FB for foods like KATKIN and wonder if all the hype and advertising claims are true? Does anyone here have experience of these foods that can give me some advice please. I'm happy to try them if they really are much better for the felines in my life.
