Panelis, part of the Diana Pet Food division, is an independent team of trained animal technicians, behaviorists and statisticians that observe and measure the consumption and enjoyment of petfood by canine and feline expert panels. Its cat food palatability testing services are now available for customers in the US and Canada through the establishment of Panelis North America and its recently opened cattery in Hodges, South Carolina, USA.

Panelis North America provides information to help petfood manufacturers make strategic decisions related to palatability. At the North American cattery, the company has approximately 80 cats that are responsible for tasting a variety of cat foods. Panelis North America says it has future plans to include a second cattery and a kennel.
