If you think your fat cat is phat, he's not.

Obesity in companion animals is a major health concern and can lead to diabetes heart disease, arthritis, chronic pain and a host of other problems, including a shortened life.

Read about Simba's weight loss journey in The Province newspaper.

A giant orange tabby, Simba arrived at the BC SPCA's Vancouver shelter in June weighing a whopping 12.5 kilograms (27.5 pounds).

Simba has already lost three kilograms and continues to lose weight under the supervision of staff and volunteers. Simba is available for adoption.

Although obesity is most often caused by guardians overfeeding their animals, it can sometimes be the product of another underlying issue. So before putting your cat on a diet, visit a veterinarian to make sure there is no medical reason for his condition.

Check out the SPCA's care and behaviour guidelines for more information on the care and feeding of your cat, dog, rabbit or other companion animal.

Tips for cat owners to help their animals maintain a healthy weight:

• Always follow the feeding instructions on the label of commercial cat foods and treats;
• Provide plenty of opportunities for your cat to exercise, such as toys and climbing posts;
• Set aside some of your cat's regular portioned kibble to offer as "treats" throughout the day;
• Use "smart" toys like treat balls for your cat so that he has to work for his reward; and
• Don't assume your cat's vocalization means he wants food, and instead try playing with or petting him.

Each year, the BC SPCA cares for almost 37,000 animals just like Simba, providing a wide range of services through its branches and clinics across B.C.  Your support of the BC SPCA October Grey Fund for Animal Care could change a life. Please donate today.
