Real Letters

Mr. Dickens, still spry for 22.
22 Year Old Cat Still Happy to Jump on Window Bench for Breakfast
Dear Springtime,
Mr. Dickens adopted us 22 years ago. He wears a tortoiseshell coat, and has outlived both his original master and his adopted master who lived to age 80. The vet's records say he was about a year old when he first saw him. He has an annual checkup, teeth get cleaned every few years – no cavities, no extractions ever. …and while he is a bit slow he has no problem jumping up on the window bench for his breakfast and dinner – breakfast is laced with J-Flex Concentrate. At the rate he is going, he may well outlast me… I became acquainted with J-Flex Concentrate from a friend who has horses. Thanks for carrying this product.
