Cartoon cat Garfield's Mid-Life Crisis Sheds Light on the Danger of Cat Kidney Disease

Online Campaign Fronted by Garfield Launches to Educate the Owners of Middle Aged Cats About Chronic Kidney Disease

MONHEIM, Germany, May 19, 2011 - A new campaign launched today will educate cat owners about the risk of
chronic kidney disease (CKD) that their pets may face as they grow older and
urge them to seek kidney function tests for cats over the age of seven. A
brand new animation featuring Garfield (as licensed by Paws Inc.) in the
midst of a mid-life crisis and a new educational website will kick the
campaign off. The website will feature a range of free downloadable tools for
owners to help them to plan for their ageing cat's health needs.

CKD is common in cats aged seven or over and almost one in three over the
age of 10 suffer from the disease.[1] It can significantly reduce a cat's
quality of life and is a leading cause of death in older cats. Early
intervention is essential to slow deterioration of kidney function, but this
can be challenging as the clinical signs of CKD are often not evident until
75-80% of the nephrons are non-functional.

"This humorous campaign is designed to educate cat owners about the
unseen risk of kidney disease as cats age and to encourage them to speak to
their veterinarian about kidney function testing," said Dr Joy Olsen, Global
Veterinary Services Manager, Bayer Animal Health. "We believe that this will
provide veterinarians with new opportunities to offer their clients both
valuable advice and treatment options - including Renalzin as a supplementary
feed for the support of renal function in case of renal insufficiency in cats
- to help them to protect the kidney health of their cats."

Renalzin(R), which effectively binds dietary phosphate even with normal
feline diets,[2] is the newest generation phosphate binder for cats.

Controlling phosphate levels is an essential part of the effective
management of CKD and can prolong and enhance quality of life. Restriction of
phosphate plays an essential role in curbing kidney secondary
hyperparathyroidism, soft tissue calcification and progression of kidney
failure.[3],[4] Often a kidney (renal) diet is the first step in kidney
therapy. Cats fed a restricted phosphate diet were shown to survive
approximately 2.4 times longer than cats fed a diet without phosphate
restriction.[5] However, cats with CKD are very sensitive to changing their
diet and often refuse this. Renalzin, which can be used with wet or dry food,
offers phosphorus control with a normal or specialist kidney (renal) diet.

Renalzin(R) binds to dietary phosphate, rendering it indigestible. As a
result it significantly (p=0.05) increases faecal phosphate excretion and
reduces urinary excretion of phosphorous which reduces the burden on a cat's
compromised kidneys. Clinical studies in cats have demonstrated the
beneficial effects of Renalzin(R). Over two months, cats given Renalzin(R)
together with a standard diet demonstrated: decrease in serum phosphate
levels, maintained or increased appetite and improvement in clinical
examination scores.[6]

Renalzin(R) is specifically formulated for cats and is simply added to a
cat's usual food. The standard recommended dosage is 2 mls applied with the
cat's food, once or twice daily depending on the cat's feeding regime.
