PT equals Pet Talk, as in the forum devoted to all things pet! It's not devoted to one animals but includes several different types of pets, like cats, dogs, horses, birds, rats, mice, lizards, any pet you own is always welcome there!
I do not know if we are allowed to link to another forum? But here is the url.
It's great to have a site where all pets are welcome, but I am really enjoying this site devoted solely to kitties, because some of the dog people get on my nerves, and there is no friend like a friend who loves kitties!
