Thank youThe only way you'll find a "softer" kibble is like to find a kibble that it still being baked and not extruded. What I food is 10% moisture and it's made with the extrusion process at is cooks at very high heat and pressure which make a very hard kibble.
Wellness was a baked kibble like 10 or 12 years ago. Last one I knew that was baked was a kibble from Triumph. Today you'd have to really search for a baked kibble.
