What is the age group for webkinz?

Their is an age limit on the tag that says not for 3 years of age younger because of the plastic code and tag but anyone can do anything so if you are really old go ahead and buy yourself a webkinz to improve our webkinz community, as far as i know their is no age limit so go ahead and buy yourself some ready......set......go P.S. I have 74 webkinz
