Pradofloxacin For Feline Upper Respiratory Tract Disease

Hartmann, A. D., C. R. Helps, et al. (2008). "Efficacy of pradofloxacin in cats with feline upper respiratory tract disease due to Chlamydophila felis or Mycoplasma infections." J Vet Intern Med 22(1): 44-52.

Two of the pathogens implicated in feline upper respiratory tract disease (URTD) are Chlamydophila felis and Mycoplasma. Typical treatment for these pathogens has been doxycycline or enrofloxacin. Both drugs are associated with adverse effects. This study investigated the efficacy of a novel fluoroquinolone, pradofloxacin, for treatment of these pathogens. In this placebo-controlled, double-blind clinical trial, 39 cats with clinical signs of URTD were divided into 2 treatment groups. One group was treated with pradofloxacin and the other group was treated with doxycycline; both groups were treated for 42 days. Clinical scores were evaluated as response to treatment. The presence of C. felis and Mycoplasma was determined by PCR analysis of conjunctival swabs. Before treatment, C. felis was detected in 23 cats, and Mycoplasma was detected in 20 cats. Both groups of cats responded to treatment with a marked improvement in clinical signs within 1 week. Complete elimination of Mycoplasma was achieved in both groups of cats. However, while all cats receiving doxycycline eliminated C. felis, 4 cats treated with pradofloxacin remained PCR-positive.

Acute Kidney Failure in Cats

Worwag, S. and C. E. Langston (2008). "Acute intrinsic renal failure in cats: 32 cases (1997-2004)." J Am Vet Med Assoc 232(5): 728-32.

Acute renal failure (ARF) is the sudden onset of impaired renal function with associated inability to regulate fluid, electrolyte and acid-base balance. The prognosis for ARF in dogs and humans is generally poor, with mortality rates of 50-60%. Very limited data has been available on the characteristics of cats with ARF. The purpose of this study was to determine the demographics, clinicopathologic findings and outcome of cats with ARF. In a retrospective case series, the records of 32 cats with ARF were examined. Causes of ARF included nephrotoxins (e.g., drugs, lily toxicity) and ischemia, among others. Increases in serum potassium were associated with decreased chance of survival. Other negative prognostic indicators were low serum albumin or bicarbonate concentration at initial diagnosis. Of the 32 cases, 17 cats (53%) survived but 9 cats had persistent azotemia. The results of this study indicate that survival rates of cats with ARF are similar to rates in dogs and that about half of surviving cats have persistent renal damage.

Feeding Practices of Cat Owners

Laflamme, D. P., S. K. Abood, et al. (2008). "Pet feeding practices of dog and cat owners in the United States and Australia." J Am Vet Med Assoc 232(5): 687-94.

The objective of this large telephone survey was to determine what and how dog and cat owners feed their pets. A random selection of pet owners were surveyed in multiple U.S. locations and 1 location in Australia. Over 1100 respondents provided data on feeding practices for 635 dogs and 469 cats. Over 98% of cat owners fed commercial food for at least one-half of the nutritional intake. In addition, 29% of cats received at least one-half of their diet from commercial canned foods, and 13% of cats were fed non-commercial foods as part of their main diet. Veterinarians were cited as the most common source of information on pet care and nutrition, but 16% of cat owners cited the internet and other media sources as their primary source of information.

Prognosis for Cats with Urethral Obstruction

Gerber, B., S. Eichenberger, et al. (2008). "Guarded long-term prognosis in male cats with urethral obstruction." J Feline Med Surg 10(1): 16-23.


This study, from the University of Zurich, evaluated 45 male cats with urethral obstruction or lower urinary tract signs due to urethral obstruction. Follow-up information from telephone interviews was available for 39 cats. Of the 22 cats with idiopathic urethral obstruction, 36% re-obstructed after a range of 3-728 days (median 17 days). Of the 10 cats with urolithiasis, 30% re-obstructed and of the 7 cats with urethral plugs, 43% re-obstructed. Most cats (51%) experienced recurrent signs of lower urinary tract disease, including obstruction. The most common reason for euthanasia was recurrent obstruction and was the end result for 21% of the cases.
