Look at what sea otters & dogs eat
From ANIMAL PEOPLE, September 2002:
SAN FRANCISCO, LONDON– Cats were accused of spreading
toxoplasmosis to California sea otters and dogs were accused of
spreading campylobacter bacteria throughout Britain in new studies
released in early July 2002–but while the allegations were quickly
amplified by mainstream news media and picked up by anti-feral cat
and anti-street dog activists, the research behind each study
overlooked key dietary factors in the transmission of the diseases.
Marine biologist Melissa Miller and colleagues with the
Wildlife Health Center at the Davis campus of the University of
California claimed in the July edition of the International Journal
for Parasitology to have traced an ongoing seven-year decline in the
population of endangered California sea otters to the fecal parasite
Toxoplasma gondi. They found the microscopic parasite in 66 of the
107 sea otter carcasses they examined.
