#308: Dr. Madonna Livingstone in Scotland, author of the textbook “Exotics Made Easy” explains how rabbits — who are prey animals — could literally be dying but projecting the message “I’m fine.” The subtle little changes in their habits are the tip off to how they really are feeling.

#306: Dr. Doug talks about geroscience, the study of the effects of aging. When does a pet become geriatric: at 70% of their expected lifespan. A ferret or rat will be geriatric at 7.

#305: Dr. Doug Mader talks about mites, which are common on rabbits and sometimes look like dandruff that seems to walk in their fur — or may appear as brown “goo” in their big ears or a crusty nose. All of these mean you need to get to the vet for swift treatment!

#296: Dr Micah Kohles of the Woodland Animal Hospital outside Lincoln, Nebraska, explains how to best care for hedgehogs, who are "charming munchkins who have become an up-and-coming pet."

#304: Dr. Doug Mader says teeth grinding in ferrets (whether when asleep or awake) is a red flag that could mean he has stomach ulcers from bacteria, just like in humans.

#292: Dr. Eleanor Spicer Rice (author of “Your Pets’ Secret Lives: the Truth Behind Your Pets’ Wildest Behaviors”) says there are spiders everywhere and you are never more than four feet from one of them — although none will cause the havoc her own curly-haired tarantula did when it let itself out of his cage.

#303: Dr. Doug talks about how rats get mammary gland tumors, a chain of glands that runs from their tail to over their shoulders, but they are benign 80% of the time and the rats often do just fine if operated on by a veterinarian experienced in small mammal surgery.

#298: Dr. Micah Kohles of Woodland Animal Hospital in Nebraska, cautions that chinchillas are not a good starter pet for a child. They are very active, not cuddlers, a bit jumpy and nervous and require very specific nutrition and a habitat with lots of vertical climbing options.
