Objectives The objective of this study was to quantify the effects of owner separation and physical examination location on fear, anxiety and stress (FAS) behavioral indicators in cats. Methods The study was a prospective, non-blinded, randomized, two-period, two-treatment crossover trial. Healthy adult cats presenting for wellness or dental evaluations at a single veterinary teaching hospital received three physical examinations: a baseline assessment (owner present) followed by physical examinations in both a treatment area (owner absent [TAOA]) and an examination room (owner present [EROP]). The physical examination sequence order was randomized. Low-stress handling techniques were used for all examinations. The primary endpoints were heart rate (HR; beats per min [bpm]) and total FAS scores. HR was measured by auscultation, and FAS by five specific behaviors scored as 0/1 and summed for each assessment period. Results Twenty-one healthy cats were enrolled. HR measured at entry (baseline) was a significant determinant of subsequent HR readings. HR measured during examinations conducted in both EROP and TAOA were elevated to levels indicative of stress (>180 bpm). HR was significantly higher for TAOA relative to EROP (30 bpm, 95% confidence interval 18–43; P Conclusions and relevance Owner separation coupled with physical examination location can result in clinically significant increases in perceived stress in cats, and compromise vital sign assessments. Whenever possible, physical examinations and procedures should take place with the owner present with separation from unfamiliar dogs and cats.

At the time of hatchling emergence from a nest laid on Juno Beach, Florida, USA, by a normally pigmented green turtle (Chelonia mydas), 23 albino hatchlings and 75 normally pigmented hatchlings were observed. This condition is rarely seen in sea turtles, and little is known about blood analytes and genetics of albino wildlife to date. Therefore, the objective of our study was to assess and compare morphometric measurements (mass, minimum straight carapace length, body condition index), carapacial scute anomalies, a suite of hematologic and plasma biochemical analytes, and two glucose analysis methodologies (glucometer and dry chemistry analysis) in albino (n=20) versus normally pigmented (n=24) hatchlings from this nest. Genetic analyses were completed to identify paternal contributions of hatchlings and to test Mendelian inheritance assumptions. Although morphometric measurements, scute anomalies, and leukocyte morphology were similar between albino and normally pigmented hatchlings, several differences were observed in blood analyte data: immature erythrocytes, packed cell volume, heterophil:lymphocyte ratio, and glucose concentrations (by both methodologies) were significantly higher, whereas absolute immature heterophils, absolute lymphocytes, number of erythrocyte micronuclei, sodium, and chloride were significantly lower in albino hatchlings compared with normally pigmented hatchlings. Considerations for these differences include a stress response from sampling (e.g., timing of procedures or possibly from photosensitivity or reduced visual acuity in albinos) and different osmoregulation, which may reflect physiologic variations or stress. There was a small positive bias (0.10 mmol/L) with glucose by glucometer, similar to reports in other sea turtle species and confirming its suitability for use in hatchlings. All albino hatchlings analyzed (n=10) were from the same father, but the normally pigmented hatchlings (n=24) were from two other fathers. These findings provide insight into the physiology and genetics of albinism in sea turtles.

OBJECTIVES To quantify the effects of wellness examinations conducted in the common treatment area on fear, anxiety and stress indicators in client-owned dogs. MATERIALS AND METHODS The study was a prospective, non-blinded, randomised, two-period two-treatment crossover trial. Client-owned healthy adult dogs presenting for wellness or dental evaluations at a single veterinary teaching hospital received three consecutive rapid assessment exams; a baseline exam (owner present), followed by two identical physical exams differing in location and presented in random order (isolated exam room with owner present versus common treatment area, owner absent). Primary endpoints were a cumulative fear, anxiety and stress score for five standardised behaviours and heart rate (bpm) measured for each exam. RESULTS Forty-four dogs were enrolled. Modal fear, anxiety and stress score at baseline was 1 of 5, indicating none to mild stress. Both fear, anxiety and stress and heart rates measured in the common treatment area were clinically elevated relative to assessments conducted in the exam room. Relative to baseline, animals examined in the common treatment area showed increased fear, anxiety and stress (+2.6 units, se 0.5; P
