Hill’s Updates Guidelines For Y/d FelineApril 3, 2012 After the launch of its Prescription Diet y/d Feline Thyroid Health pet food last year, Hill’s Pet Nutrition Inc. of Topeka, Kan., has released an updated set of guidelines and algorithms to assist veterinary care providers who are managing hyperthyroid patients with the food. Hyperthyroidism is one of the most common diseases in middle-aged and older cats. Resulting from too-high levels of thyroid hormone (T4) and increased metabolism, the illness can cause a range of clinical findings, from hypertension to ravenous appetite, weight loss and excessive urination. Some cats also have concurrent kidney disease. Traditional treatment options have included radioactive iodine, the medication methimazole to control levels of thyroid hormone, or a thyroidectomy. A decade in the making, Prescription Diet y/d Feline gives veterinarians a new management tool—and so far, says David Bruyette, DVM, Dipl. ACVIM, medical director of VCA West Los Angeles Animal Hospital, it has been working. Since June, Dr. Bruyette and his veterinary health care team have been using the therapeutic cat food to manage newly diagnosed feline hyperthyroid patients and those previously diagnosed that are transitioning from anti-thyroid medication. “What we’ve seen …

FHS May Have Underlying Schizophrenic LinkApril 3, 2012 Feline hyperesthesia syndrome (FHS) is an enigmatic and controversial behavioral and medical condition that most often affects Oriental cat breeds. I saw my first case many years ago in a Siamese cat that displayed the three cardinal signs: excessive skin rippling or twitching (hence the alternative designation “rolling skin disease”), bouts of manic self-grooming, often initiated by stroking the cat along its back (”hyperesthesia”), and widely dilated pupils during bouts of the behavior. The cat had just bitten one of our students, who was trying to restrain him, sending the student to the hospital for intravenous antibiotic treatment. Mercurial aggression, while being restrained, is another feature of FHS in some cats. Other odd behaviors associated with the syndrome include periods of freezing in position while staring vacuously into space, sudden bouts of running away from what appears to be some unseen enemy and apparent hallucinations (visually following things that aren’t there). Learning More In the early days, feline hyperesthesia syndrome was described as a compulsive disorder or stereotypy, but over time I became skeptical of the label to the point where I now consider it incorrect. The first seeds of doubt regarding the compulsive disorder …
Fabulous Feline Fling!March 26, 2012 Close your eyes, and imagine this…well, you can’t read this if your eyes are closed, so have someone else read it to you with your eyes closed…but not if that person is a prankster, because something bad might happen to you while you’re closing your eyes…so use your best judgment. So where were we? Ah yes, telling you what to imagine. I would have loved to get photos for you, and I did get a digital recording, but I’m not so sure they want this running on VPN’s website! It was a few mornings ago. I walk into the kitty palace, the room in which my four cats nap and eat, and the first thing I notice when I open the door is green plant material on the floor. Now we have bunnies, too, so my first thought is hay. But no, I open the door a little more and find the large plastic sack that used to hold all of their catnip, but now most of it is spread out on the floor! I open the door a little further, and see plastic trash bags askew in the room. Hmm, now they are usually stored …
The Case Of The ‘Tummy Tuck’ I Just Couldn’t Get PastMarch 21, 2012 If I hadn’t seen it for myself, I wouldn’t have believed it. A pre-vet student who works for me finally wore me down and convinced me to Google it. That’s when I settled in with my morning coffee to watch a 30-minute video on the merits and how-tos of “tummy tucking” for cats. Tummy-tucking? Seriously? Apparently. And it was awful (as you might have expected it would be). In this case, undertaken in a mobile surgical unit on what appeared to be a middle-aged domesticated shorthair female with an average-sized “belly pooch,” the cat was subjected to a 30-minute procedure dedicated to removing as much subcutaneous fat as possible. Horrible. More so when you consider that one of the major complications with liposuction (done in humans with “lipo-wands” designed for the task) is the potential destruction of blood supply to the overlying skin and, therefore, full-thickness skin necrosis. This complication is rare when the procedure is performed correctly, seeing these wands are specifically designed to leave major vessels intact. But in the cat and dog (distinct from humans) the blood supply to the overlying skin is even more tenuous. While humans have multiple musculocutaneous vessels scattered …
For ToboMarch 21, 2012 Like many service members returning from war, Army Capt. Sam Wilson brought back from Iraq mental images and experiences that made home life a struggle. The love of his wife and pets helped ease his transition, but still there were flashes of anger that sent him searching for solutions. One solution was named Tobo. The German shepherd came into his life after his wife, Kris, suggested he answer an ad in the paper. “I think she just knew I needed that companionship,” recalled Wilson, now a statistician for a clinical research organization. “You know how you can have lots of pets but there’s always one that holds a special place for you? Tobo is that one for me.” So after watching Tobo, now 8, lose mobility and suffer through the pain of hip dysplasia, arthritic inflammation and degenerative joint disease, Wilson was excited to get a phone call last fall from the family’s veterinarian, Chuck Miller, DVM, a partner at Triangle Veterinary Hospital in Durham, N.C. Prime Candidate Dr. Miller, who in June will mark his 20th anniversary as a veterinarian by continuing to practice at a clinic that has been around since …
Update On Hospice PatientMarch 16, 2012 For those of you following my blog, you know that my 14-year-old Somali cat is currently in hospice care for suspected infiltrative GI lymphoma. We were given a rainbow of hope when we started Prednisolone, even though it upset me to move to the “last step” in her treatment. In other words, the Pred is the last thing we can do to help her. I knew this, so starting it seems like the end. But she rebounded so nicely, started putting weight back on and grooming herself more. Then we fell under the delusion that maybe she isn’t sick after all? My friend the hospice nurse said this was normal, families begin to feel like maybe the end isn’t coming, because the animal responds so well to the treatment. Yet she warns, it’s just that the palliative care we are giving her is working, for now. In practice, we often have families who cling to the last little bit of hope. Sometimes it borders on denial, and it’s difficult to make them understand that their pet is suffering. This is particularly true because most people don’t understand how a pet demonstrates …
Cats From Hell?March 12, 2012 So are any of you watching the show My Cat From Hell on Animal Planet? What a show! At first I was skeptical; who is this Jackson Galaxy dude, what kind of name is that, why does he shape his facial hair like he does, why does he carry his cat equipment in a guitar case, and most importantly, what credentials does he have that makes him a cat behaviorist? Being a cat person myself, I couldn’t help but watch a few episodes to see what happens…and now they are set up to record on my DVR! From what I can tell, he learned cat behavior by working with shelter cats who were trying to get rehomed. I’m not sure if he has any true credentials in cat behavior, but I tell you, he knows his stuff. They show some of the nastiest cats I’ve ever seen. They lunge at the people in the house, they terrorize each other when there are multiples, they pee in the sink and on the carpet, and one even climbed a trellis out on the back patio, opened the neighbor’s screen door, and stalks her at her own house! What is …
A Tetraplegic Recovers Without SurgeryMarch 6, 2012 Kelvin, a 50 pound, 4-year-old female spayed Husky mix was in bad shape. She presented with progressive weakness in all four limbs. Her recent history included a mild bout of diarrhea, which was (still) treated with 500 mg metronidazole BID. The day the dog was referred for an MRI, she was unable to walk on all four limbs. There was no obvious cervical spinal pain and she was tetraparetic (i.e. weak and unable to stand or walk). She appeared tense all over her body and “nervous” or “stressed out.” Blood work was unremarkable. The rest of the physical exam, including heart auscultation, was normal, except for obesity (body condition score of 5/5). A cervical spinal MRI was performed. The radiologist, who read the pictures in real time, deemed the scan normal. Therefore, an MRI of the brain was performed. It was normal, as well. The dog was referred to an internist. The diagnosis was central vestibular disease due to… metronidazole toxicity. Full disclosure: This patient was not mine, but I thought it was an interesting case that was well worth a quick review of metronidazole toxicity to avoid “getting caught.” The important thing to …
Cracking Fevers Of Unknown OriginFebruary 13, 2012 Fever can indicate infectious, inflammatory, immune-mediated or neoplastic disease. Typically, a physical examination and medical history lead a practitioner to a fever’s cause. Or the fever resolves serendipitously or in response to antibiotic therapy. But in some cases, the underlying cause of the fever is not readily apparent. These patients are said to have a fever of unknown origin (FUO). In 1961, the acronym FUO was coined by medical doctors Robert Petersdorf and Paul Beeson and defined as a temperature greater than 101 degrees Fahrenheit on several occasions, illness for more than three weeks and failure to reach a diagnosis despite one week of inpatient investigation. According to the Merck Veterinary Manual and veterinary specialists, this syndrome has no recognized definition in veterinary medicine, making its prevalence difficult to determine. “FUO is common in both species [canine and feline], although underlying causes can be quite different,” says Craig Webb, DVM, Dipl. ACVIM, Ph.D., MS. “Unfortunately, these cases often require that we try to rule out almost everything,” continues Webb, an associate professor of internal medicine at Colorado State University’s College of Veterinary Medicine and Biomedical Sciences. “So after the history and physical examination we …
The Bossy Cat And Owner-Directed AggressionFebruary 8, 2012 Owner-directed aggression in dogs has been written and talked about at length, but feline owner-directed aggression has received less attention. In dogs, “conflict aggression” has replaced “dominance aggression” as a more accurate description of the behavior’s motivation. The change occurred because pundits no longer accept the premise that the relationship between dogs and their owners is governed by pack mentality, as neither dogs in the wild nor, as it turns out, wolves seem to organize themselves along these lines. With this in mind, it seems ludicrous to discuss dominance or status-related aggression in cats, as they do not organize themselves into packs and should have no biological drive to establish themselves in any kind of order. But is it so ludicrous to consider that there may sometimes be a particularly bossy cat that calls the shots with others in a household? I think not. One social arrangement of cats has been described as a “despotic hierarchy,” a system in which one cat assumes control over all others who, barring the odd pariah, live peaceably as subordinates. Another more fluid, social situation between house cats involves a sort of time share arrangement in which one cat may …
