Being born with a deep interest in animals might seem unfortunate for a native Bronxite , but my family encouraged my interest and the menagerie that sprung from it. Jobs with pet stores and importers had me caring for a fantastic assortment of reptiles and amphibians. After a detour as a lawyer, I was hired as a Bronx Zoo animal keeper and was soon caring for gharials, goliath frogs, king cobras and everything in-between. Research has taken me in pursuit of anacondas, Orinoco crocodiles and other animals in locales ranging from Venezuela’s llanos to Tortuguero’s beaches. Now, after 20+ years with the Bronx Zoo, I am a consultant for several zoos and museums. I have spent time in Japan, and often exchange ideas with zoologists there. I have written books on salamanders, geckos and other “herps”, discussed reptile-keeping on television and presented papers at conferences. A Master’s Degree in biology has led to teaching opportunities. My work puts me in contact with thousands of hobbyists keeping an array of pets. Without fail, I have learned much from them and hope, dear readers, that you will be generous in sharing your thoughts on this blog and web site.

Keeping and Breeding the African Pygmy Mouse – Part 1

Pygmy MouseThe African Pygmy Mouse (Mus minutoides) is a delightful little creature that is sometimes available in the US pet trade.  Its care differs slightly from that of its giant (by mouse standards!) cousin the House Mouse, but experience with House or Fancy Mice will be very useful should you decide to give these diminutive fellows a try.

Note: Be sure to check local laws before purchasing an exotic rodent, and ask your doctor if there are any health issues to consider.  All animal bites and scratches, however minor, should be attended to by a physician. Read More »

Domestic Cat Origins – Is Your Pet Merely a Tame Wildcat?

European WildcatCat owners quickly notice how closely their pets’ behavior follows that of their wild relatives…in fact, Domestic Cats are classified by many mammalogists as a subspecies of the Wildcat.  Recent research has shed light on the Domestic Cat’s true ancestor and its original time and place of domestication.

Supreme Survivors

Domestic Cats slide seamlessly from indoor to outdoor life, and their adaptability amazes biologists who study feral populations.  Those living in one Australian desert never encounter standing water, yet get along quite well; a group shipwrecked on Marion Island, off the tip of South America, thrives in the shadow of Antarctica – further south than any other non-marine mammal!

Adaptability has helped the 5 subspecies of the Wildcat (Felis sylvestris) to survive in habitats ranging from Chinese deserts to African village outskirts (please see map).

Domestication Theory Overturned

The Near Eastern or African Wildcat (please see photo) has commonly been credited as the ancestor of the Domestic Cat.  Because of its prominence in ancient Egyptian culture, it was believed that Wildcats were the first domesticated there.  Based on archaeological studies, the time of domestication was given as approximately 4,000 years ago. 

The discovery of a 9,500 year-old apparently Domestic Cat in a tomb in Cyprus set the domestication date much further back in time.  Wildcats are not native to Cyprus – the animal is believed to be a Near Eastern Wildcat, taken there by people from Turkey (please see article below).

Wild Ancestor(s)

Each of the 5 Wildcat subspecies – the European, Near Eastern, South African, Central Asian and Chinese Desert – interbreed among themselves and with feral Domestic Cats, so the ancestor of our pets could have been any of these.  Advances in genetic studies, however, has now given us a definitive answer.

Researchers at the US National Cancer Institute and the University of Oxford analyzed DNA from all 5 Wildcat subspecies, and determined that the Near Eastern Wildcat (Felis sylvestris lybica) gave rise to the modern day Domestic Cat, and that the site of original domestication, some 10,000 years ago, was in the area known as the “Fertile Crescent”, in what is now Iraq.

This finding coincides nicely with other evidence.  The cat’s association with people came when grains were first being cultivated and stored…the cat’s prowess as a rodent killer would have made it a welcome guest.  Interestingly, Near Eastern Wildcat kittens are relatively easy to tame and even today they often reside near people and interbreed with Domestic Cats.  Not so with all Wildcats – colleagues of mine contend that the European Wildcat (please see photo) is impossible to tame, even when bottle-raised!

What is a Domestic Cat?

African WildcatThe traditional definition of a species is the ability to mate and produce fertile young – Domestic Cats do so with all Wildcat subspecies.  Many taxonomists, therefore, classify the Domestic Cat as a Wildcat subspecies, Felis sylvestris catus, rather than as a distinct species (F. catus).

The odd appearance of a young Bobcat I once trapped led me to believe that one of its parents was a Domestic Cat, but experts are split on this possibility – more on that in the future.

Animal Shelter Volunteers – Having Fun While Helping Creatures In Need

Animal fans often have difficulty finding hands-on animal work, and most animal shelters are underfunded and cannot hire enough help.  Volunteering at a shelter is, therefore, a win-win situation….as most who have volunteered at anything will attest, the helper benefits as much as the “helped”.

Typical Volunteer Duties

Hands-on animal work at shelters may involve walking, grooming or bathing dogs, cleaning cages and preparing food.  Many volunteers find interacting with dogs, parrots, cats and other animals in need of human contact to be a very pleasurable aspect of their experience.  In doing so, they make the residents’ stay more pleasant, and fulfill their desire for close contact with a variety of creatures.

People with other skills can often help out in office work, fund-raising or educational programs. Read More »

Exotic Pet Possibilities, Part 2 – Sugar Gliders, Degus, Hedgehogs and Spiny Mice

Sugar GliderPygmy Mice, Ground Squirrels, Civets – all sorts of interesting small mammals have found their way into the pet trade and are regularly being bred.  Please see Part I of this article for a look at my favorite, the Flying Squirrel. Today I’d like to introduce several others that I’ve enjoyed keeping and learning about.

Note:Please see Part I of this article for health-related and legal considerations.  Read More »

Exotic Pet Possibilities – Part 1 – Flying Squirrels

Flying SquirrelAn amazing array of unusual small mammals have long been bred in captivity and sold within a rather small circle of exotic pet enthusiasts. Some, such as Fennec Foxes and Bennett’s Wallabies, are suitable only for well-experienced keepers with ample room and resources while others, including Servals and Coatimundis, can be downright dangerous and are best enjoyed in zoos or the wild. Today I’d like to introduce an animal that, while not suitable as a “first-time pet”, is a great choice for experienced hobbyists looking to expand their pet-keeping horizons. I’ll cover captive care in greater detail in future articles and move on to Sugar Gliders, Degus, Hedgehogs and Spiny Mice in Part 2.

Note: Be sure to check your state’s laws regarding exotic pets…please write in if you need help in locating this information.

It is imperative that you locate an experienced exotic mammal veterinarian before deciding to keep any of the animals mentioned below. You should also consult with your family doctor regarding any potential health hazards. Read More »

Feral Ferrets – Domestic Ferrets Gone Wild!

The domestic ferret did not originally exist as a distinct species, but rather was produced via selective breeding of its wild relative, the European polecat (Mustela putorius).  Please see our article Ferret Facts for more information on the ferret’s surprising history.

Despite centuries of domestication, ferrets retain many of their wild ancestors’ instincts.  In the following article, we’ll take a look at the “wild side” of ferret life.

Domestic Ferrets in the Wild

Both ferrets and polecats have been released in New Zealand (1879-1886) as a rabbit control measure.  Today a huge population of ferret-polecat hybrids occupies the island.  Along with introduced stoats (a Eurasian ferret relative) and weasels, they have decimated populations of several flightless birds…the rabbits remain relatively unphased!  Read More »

Animal Cruelty and Abuse – Understanding the Law and Reporting Violators

Lab_animal_careDespite the many people and groups involved in animal welfare and conservation, the sad fact is that animal abuse and neglect remains a serious problem USA.  Unfortunately, the relevant laws are quite confusing and lack uniformity, and it is often difficult which agency is responsible for enforcing them.  It is worthwhile, however, to learn as much as you can about how to proceed – most enforcement authorities are poorly staffed, and rely almost exclusively upon citizen complaints for leads.

State and Federal Laws

Animal abuse is a crime in all 50 states, and almost all aspects of the problem are controlled by state law.  The only areas covered by a federal law (the Animal Welfare Act) are commercial animal breeding facilities, zoos, circuses and research labs.

Details, such as what constitutes abuse or neglect and how the laws are actually enforced, vary from state to state.  In some states, various types of illegal situations (i.e. dog-fighting, neglect in pet stores, abused animals in private residences) are handled by different law-enforcement agencies.  Read More »

A 140 Pound Guinea Pig?…Capybaras and other “Zoo Pets”

Life as a zookeeper provided me with countless unforgettable experiences.  I place rearing orphaned mammals – creatures I never expected to see up close, much less handle – right at the top of my list.  I’ve had the great fortune to have raised a number of species (i.e. Snow Leopards, Gorillas, Wolves, Red Pandas), but it is the good-natured Capybara that I remember most fondly.

Observations in Venezuela

Largest of the world’s rodents, Capybaras inhabit river edges and flooded grasslands from Panama to northern Argentina.  Quite common on a cattle ranch in the Venezuelan llanos where I was involved in Green Anaconda research (please see Hunting Anacondas in the Venezuelan Llanos), I was able to spend a great deal of time observing them.

Near the ranch buildings, they were quite tame, even wandering through open doors on occasion.  The Capybaras that lived further out on the llanos, however, were entirely different creatures.  Their meat is considered a delicacy, and they have learned to charge headfirst into the water, uttering their strange “barks”, upon sighting people.

A Capybara Ruins my Film…

The Capybara is a highly social animal.  Females are very protective of their

young (I’ve seen them stand between intruders and their litter on many occasions), and the dominant male will try to hold off a threat while his harem flees.

Well, not always…while explaining this very behavior during the filming of a sequence on Capybaras, I was made to look foolish by a male who considered chivalry quite dead.  Approaching a group by boat and with my back to the Capybaras, I rambled on about the male’s soon-to-be-seen valor.  Noticing my colleagues laughing hysterically, I turned to see him disappearing into the brush, leaving his females and offspring unprotected and confused!

Capybaras as “Pets”

Baby Capybaras, or “Chiguires”, as they are known in Venezuela, are often taken in and raised until their care becomes too much of a burden (multiply your Guinea Pig’s droppings a thousand-fold, add the need for a pond, and you’ll see why they are not ideal house pets!).  After that, they are kept at semi-liberty – feeding largely on their own but returning to their adopted families regularly.  On many Venezuelan ranches, Jaguar, Puma, Caiman and Anacondas render life dangerous for a solitary Capybara unschooled in the ways of the wild, and I imagine that some meet their end when they wander too far afield.

I cannot recommend a Capybara as a pet – their teeth are not to be believed, and throughout their range stories persist of hunters and horses killed by bites that severed leg arteries.  And no matter how well adjusted, any wild animal remains wild – those that become very calm are in a sense all the more dangerous, as it is easy to forget that they are not domesticated.  However, cared for in a zoo setting, by well-experienced keepers, Capybaras make ideal animals for use in educational programs.  They are just as responsive as their cousins, the Guinea Pigs, and readily bond to people who care for them…and it’s hard to put into words the looks on the faces of children when a “tame” Capybara enters the classroom!

I was surprised to learn that a small population of Capybaras – released pets, no doubt – thrives in northern Florida.  For more info, please see this article.

 

A Naturalist-Priest, Yellow Rats and Bacterial Research – The Contorted Story of the Gerbil’s (Meriones unguiculatus) Arrival in the Pet Trade

In 1862, a French missionary named Armand David was commissioned to China, ostensibly as a school teacher.  However, the young priest had been deeply interested in nature since childhood and, as naturalists are want to do when finding themselves in exotic (or familiar!) locales, he began to collect all that walked, swam, flew or grew within reach. 

A Missionary’s “Alternative” Calling

The specimens he sent back to France intrigued the director of the Natural History Museum in Paris, and funding allowing Father David to continue his collecting was soon arranged.  From 1866 to 1874 he explored largely unstudied regions in northern and western China, and was eventually responsible for bringing hundreds of previously un-described species of animals and plants to the attention of European biologists.
