I think it's a great idea, there are many people here on JSP who love to brag about how cute their dog is, or their cat. I even saw people brag about their fish!!!
What I'm trying to say is that many people on JSP own pets, some own some very rare pets as well, and I think that everyone would be able to chat about them there.
This section can also help people when a pet is sick or unhappy. It can also encourage people to get a pet seeing how fun it is.
Let me know what you think, I believe that the section will be really active
That's what the "off-topic" forum is for.
