Kate and Steve O'Brien have launched SlimKitty.com, a site that focuses on the health of cats. The site is sister to SlimDoggy.com, which highlights canine health.

The sites aim to raise pet owners' awareness to the issue of pet obesity and educate owners about food, nutrition and the importance of exercise for the health and longevity of their pets. "We want [pet owners] to know what's in the food they are feeding, recognize how much they are feeding and understand how both factors impact their pets' health and longevity," said Kate O'Brien. "Just as with dogs, overweight cats are more susceptible to obesity-related diseases, particularly diabetes, as well as osteoarthritis and liver and kidney problems."

SlimKitty has a database with more than 1,000 cat foods so far that tracks ingredients, nutrients and calories. The SlimDoggy database is at 3,000 dog foods. "SlimKitty is just starting out, but our hope is to gain a following of caring, concerned cat owners who want to feed their cats the best they can feed them while also making sure their cats stay fit through activity and exercise," said Kate O'Brien. "We all love our pets and want what’s best for them. What could be better than a long happy, healthy and fit life?"
