On Petpav.com, pets aren't just welcome, they're the main attraction. And there's no danger of their profile being taken down by Facebook's pet police. Founder Lisa Fimberg launched the site because she wanted to create a social network where people and pets could connect with one another. "Petpav is all about our pets," Fimberg explains. "It's a safe and friendly place to talk about your pet(s) and the pet owners love and embrace it."
