I would be utterly remiss if I didn't tell you all about the delightful and informative Worms and Germs blog, brought to us by the University of Guelph Centre for Public Health & Zoonoses in Ontario, Canada. Apparently there is someone in the world with an even greater obsession with zoonoses than me - orders of magnitude greater. And he's a much better writer.
Where else can one learn about 60 lb beavers attacking small children, tarantula hair damage to the eyes, and the appallingly bad advice given to pregnant women by "expert" pediatrician T. Berry Brazleton?
Worms and Germs also has this excellent fact sheet on basic safe cat ownership. And let's not forget about our rabbits and hamsters!
