A calm cat is a happy cat. Today's cats have a different lifestyle than their ancestors, and for some this leads to periods of more stress. Our diet contains a special blend of tryptophan and L-casein, both clinically proven to help reduce anxiety-related behaviours in felines. These bioactive compounds can also help reduce the incidence of stress-related health conditions in felines. These are the same natural substances that the cat mother pass on to her kittens via her milk, and gives the kittens a feeling of peace and safety.
