His Patients Go Into a Recovery Cage

The tumor, a subcutaneous growth the size of a Ping-Pong ball, must be removed.
Dr. Tom Reed, the surgeon, puts on his gloves. His assistants have administered the anesthesia and shaved the patient's chest. Precise and efficient, Dr. Reed makes a cut no longer than three-quarters of an inch and gets to work. The mass he extracts is almost perfectly round and self-contained. The operation, which took less than four minutes, produces remarkably little blood.
"He's so quick there's no time for blood," said Steve Gardner, a colleague of Dr. Reed's who has entered the operating room.As he sews up the patient's chest with four small stitches, Dr. Reed, a man of few words, grows ever so slightly chatty. The stitches are stainless steel wire.
"We do that so she won't chew them off," he said.A minute later, the patient, a one-year-old rat named Zver, is awake and appears to be listing slightly but otherwise faring well. As the assistant places Zver in a recovery cage, a heating pad tucked underneath for warmth, Dr. Reed takes a look. "Her coloring makes her look a little like a ferret, doesn't it?" he said.
"They're born tame, but they have to be exposed to humans so they'll bond with them when they're young," said Debbie Ducommun of Chico, Calif., also known as the Rat Lady. "You can take an older rat and socialize it, but it won't be quite as trusting."Ms. Ducommun, who operates a Web site (www.ratfanclub.org) for rat fans, said that when she started out as the Rat Lady in 1985, hamsters were by far the most popular pocket pet. Now, in California, still a trendsetting state in at least this regard, rats appear to be more popular than hamsters.
Hard numbers supporting this claim are difficult to come by, but Ms. Ducommun said that 11 years ago she began calling pet stores to do her own informal surveys. "In 1992, they were still selling way more hamsters than rats," she said. "Now pet shop owners try to steer people toward rats instead of hamsters," said Ms. Ducommun, who has 20 rats of her own, most of which she rescued from a pound after their owners decided they could not afford to keep paying the medical bills.
Alex Rincon, the manager of Your Basic Bird in Berkeley, said this was certainly the case at his store. "Rats are much more social than hamsters," he said. "They like to hang out with you, and they're not crabby the way a lot of the hamsters are."
Ms. Ducommun attributes the rat mania in California to the relative openness of people here toward new things. "If you find out that rats make good pets, maybe a Californian would be more likely to follow that up," she said. "Whereas someone in another state might brush it off and say, `You've got to be kidding.' And then there's a snowball effect." As objects of affection go, rats are rather fleeting. The average life span of a pet rat is two years, the latter half often spent coping with various diseases. Not only are benign mammary tumors like Zver's common in female rats starting at around 18 months, when rat menopause hits, but so are respiratory ailments and unpleasant skin conditions.
Dr. Reed is careful to point out that the rats he treats are not the wild sewer rats that annoy, bite and generally spook New Yorkers. Nor are they the roof rats that infest people's homes. They are a tame variation on Norway rats, which are thought to have evolved from ship rats over the last 1,000 or so years.
Dr. Reed, 58, a tall, lanky man with a handlebar mustache that descends a good four inches below his chin, did not set out to be a rat specialist. Things just turned out that way. His veterinary training is in orthopedic surgery, and he operates on most of the animals that come in for surgery. Thirty years ago, not long after going into practice, he treated his first rat.
The practice doesn't make much money on rats. It costs the office nearly as much to perform surgery on them as on dogs or cats. Yet Dr. Reed sees how attached people grow to their rats, which is in part what motivates him to do what he can for them. In recent years, as word of his rat expertise has spread, mostly via the Internet (although the doctor himself does not own a computer or go online), rat owners have come from neighboring counties to have their rats' tumors removed.
