 By the end of March, veterinary organizations reported more than 100 pet deaths amongst nearly 500 cases of kidney failure, and experts expected the death toll to number in the thousands, with one online database already self-reporting as many as 3,600 deaths as of 11 April.The U.S. Food and Drug Administration has received reports of approximately 8500 animal deaths, including at least 1950 cats and 2200 dogs who have died after eating contaminated food, but have only confirmed 14 cases, in part because there is no centralized government database of animal sickness or death in the United States as there are with humans (such as the Centers for Disease Control).For this reason, many sources speculate the full extent of the pet deaths and sicknesses caused by the contamination may never be known.
