Meet the fat pets on a mission to lose weight

Meet the fat cats and dogs working hard to drop their excess weight in the PDSA's annual fat-fighting competition.
The PDSA's annual 'Pet Fit Club' has begun and the UK's fattest cats and dogs are now on a mission to shed their excess weight. Over the last eight years, the contest has changed the lives of some of Britain’s biggest pets. Zed the Border Collie is now working with head nurse Helen Darnell to drop the pounds.

The Pet Fit Club was launched in 2005 and has already helped 57 dogs, 24 cats and 3 rabbits lose a total of 295kg (46stone 6lb). That's the equivalent of nearly 300 bags of sugar, more than 4,400 sausages and 740 tins of dog food. This White Shepherd Wolf weighs a whopping 10st 9lb!

Senior veterinary surgeon, Elaine Pendlebury says: "Pet obesity significantly increases the danger of developing major health problems such as diabetes, arthritis and heart disease and can also bring about the onset of these chronic diseases much earlier. It’s tragic to think that millions of pets are suffering under the strain of carrying too much weight, when it is an entirely preventable condition.” Nurse Amanda Shearsby is with Lucky the cat.
