NetKittenz

NetKittenz are stuffed cats, online and offline. They are a play on Webkinz, a popular toy.

Emily and D.W. both have one of these virtual pets, with the names Tickely and Prince Shiny. Arthur says that every kid he knows that are D.W.'s age are obsessed with the toys, meaning that they are a fad.

Netkittens are extensively customizable, judging from the local Grebes accessories that Mr. Ratburn and Arthur were able to buy for D.W.'s Netkitten. This is a difference from Webkinz.
