Senior Bits Joint Support are small, delicious parcels filled with a core of valuable joint support nutrients. Joints suffer a lot of wear and tear during a cat’s life and in cats over 7 years of age it is much more common for the joint cartilage to progressively wear away. These treats contain Collagen Hydrolysate and natural Glucosamine from shellfish and crustaceans; supporting joint mobility and helping promote the natural re-generation of cartilage over the longer term.
