I rescued Puss’n as a mature cat from a shelter in Oakville Ontario 16 years ago. About 6 years ago, on a friend's recommendation, I switched both Puss and my Golden Retriever from the brands that I was giving them. Puss has been alternating between Indoor Mature 27 and Special 33 but last week I bought Aging 12+ and I started by giving him a couple of kibbles as a treat... he went crazy! Meowing and clawing at me for more! We laughed hysterically because we’ve never seen him act like this before.
