From the Allerca Web site: The Allerca kittens will be delivered to customers via their local veterinarian and will become generally available in the first quarter of 2007. The Allerca kittens come with premium pet insurance provided by Pets Best, are micro-chipped, and are spayed or neutered. Along with a care pack provided to help a family raise their new kitten, each Allerca kitten comes with a unique Certificate of Authenticity that shows an actual image of its divergent gene sequence. Each Allerca cat is priced at $3,950 and a waiting list already exists.

"It's not about the money for people who always wanted a cat but couldn't because they or someone they knew was allergic -- it's about an investment in a family companionship that can live up to 12 years on average. It's hard to put a price tag on that," says Dr. Cruz.
