"Anipals," as pets on Twitter are sometimes called, have carved out an entire universe in which they, with a little help from their owners, hold monthly parties to raise money for rescue groups, give shout-outs to ailing animals, trade pictures and chronicle the day-to-day meanderings of their keepers.
Of all the critters on Twitter -- and there are an estimated 69,000 pet profiles -- cats command the largest followings. (Perhaps, as one cat owner told the New York Times' Bits Blog, cats simply have more to say.) Sockington, a Persian cat in Waltham, Mass. remains the most popular non-human on Twitter, with his own blog and more than 1.5 million Twitter followers, more than Wyclef Jean or Dr. Sanjay Gupta. And Romeo the Cat has gotten his army of more than 8,000 followers to give $32,000 to various animal rescue groups.
Dogs, ferrets, birds and other creatures also have a place on Twitter. FrugalDougal, a cairn terrier who lives in England, is the online director of the PawPawty, an international monthly get-together that occurs solely on Twitter to raise money for animal charities. Created by FrugalDougal's owner, Lynn Haigh, the events feature "bark tenders" who mix up special virtual cocktails (flavored milk for the youngsters, adult drinks like Pina Catladas and pawjitos for the older anipals) and anipal "sekurity" to keep out spammers. Attendees are encouraged to donate to a chosen charity. In the first year, the parties raised $25,000.
