Davis Study Finds Possible Link to Pet Food Deaths
Written by C. Johnson, Internet News Producer

UC Davis researchers have found two chemicals that in combination may have contributed to cat deaths leading to a pet food recall earlier this year.

The two chemicals are melamine and cyanuric acid. Melamine is used to make plastic and cyanuric acid is helpful at retarding the breakdown of chlorine in pools and hot tubs.

Early lab studies confirmed the presence of melamine in some of the tainted cat food; however, the discovery of cyanuric acid was a surprise, according to the Davis researchers.

Veterinary toxicologist Birgit Puschner and her colleagues determined that fan-shaped crystals developed in the urinary tracts of cats given both melamine and cyanuric acid in their food. Those cats suffered severe kidney damage within 12 hours of eating the adulterated food.

The study found that felines which received food containing only melamine or cyanuric acid did not have ill effects.

Last April, more than 100 brands of tainted cat and dog food were recalled.

The UC Davis research can be found in the November issue of the Journal of Veterinary Diagnostic Investigation.
