Abstract
Physical examination did not detect any palpable testes within the scrotum; however, spines were detected on the penis. Abdominal ultrasonography revealed a mass in the region of the right adrenal gland. Results of adrenal hormonal analyses revealed considerable increases in serum concentrations of...

Abstract
Overall, 1,361 of 2,624 (51.9%) dogs and cats had health problems 1 week after adoption, and 239 of 2,312 (10.3%) had a health problem 1 month after adoption. The most common health problem for dogs and cats was respiratory tract disease. A total of 1,630 of 2,689 (60.6%) respondents had taken their...

Abstract
There are many common issues that owners find problematic with their puppy's or kitten's behavior, such as eliminating in inappropriate locations, chewing, mouthing, growling, and biting. Many of these issues can be prevented or managed by helping owners understand normal canine and feline behavior...

Abstract
Anxieties and fears play a large role in some of the more common feline behavior problems. The interaction between emotions and stress is complex but pertinent to the field of veterinary medicine, given the physical and emotional consequences of stress in animals. By thinking of behavior "problems"...

Abstract
In urban areas, there may be a high local risk of zoonosis due to high densities of stray cat populations. In this study, soil contamination by oocysts of Toxoplasma gondii was searched for, and its spatial distribution was analysed in relation to defecation behaviour of cats living in a high-densit...

Abstract
The authors examined pre- and postpartum open-field (OF) behavior and maternal responsiveness in mice that they bidirectionally selected for OF thigmotaxis. The authors tested 40 female mice under 3 conditions: prepartum OF, postpartum OF, and a pup retrieval test. In both OF conditions, the high OF...

Abstract
Decreasing litter box odor may be an important treatment component in addressing feline inappropriate elimination. A three-phase study was conducted to determine if the use of Zero Odor litter box spray increases the preference of litter boxes to cats, presumably by its odor-eliminating quality. In...

We found an inverse association between age of the dog at acquisition and risk of unsuccessful dog ownership: the younger the dog at acquisition the higher the risk. The incidence-proportion ratios (IPRs) of unsuccessful dog ownership for the owners who had a history of pet abandonment or losing a p...

Abstract
We determined that vasopressin acted via vasopressin 1a (V1a), but not V1b, V2, or oxytocin receptors, whereas tachykinins acted via neurokinin 1 (NK1), but not NK2 or NK3, receptors. Vasopressin acted by enhancing a nonselective cationic conductance; in some motoneurons, it also probably suppressed...

Abstract
Litter box location did not differ between cats with and without elimination behavior problems. An inverse correlation was found between time spent sniffing and the distance of the litter box from the central core area. Cats with elimination problems spent significantly less time digging at the litt...

Abstract
Correlations between meal size and inter-meal intervals as a characteristic of ingestive behavior are generally calculated utilizing Pearson's correlation coefficient. However, this commonly used method may exhibit disadvantages and methodological problems when dealing with dependent time series. Al...

Whereas foraging has been a major focus of ecological and entomological research, its obligate partner, defecation, has been comparatively neglected. Insects exhibit a range of intriguing behavioral and morphological adaptations related to waste disposal in a range of contexts, including predator-pr...

Abstract
We studied how the nervous system selects between noxious stimulus-evoked withdrawals and micturition, movements that are necessary for survival but use overlapping muscles and therefore cannot occur simultaneously. In lightly anesthetized rats, micturition was favored, because noxious stimulation n...

In the month following adoption, 64 (50.8%) kittens were reported to have at least 1 of the 3 behaviors. There was no evidence that the 3 behaviors were related. The percentage of kittens reported to urinate or defecate outside the litter box decreased from the first to second evaluation and remaine...

Abstract
Although challenging at times, managing cats with elimination issues can be rewarding. The frustration in management of these cases is often a result of the lack of a proper diagnosis and random treatment application. A systematic approach to these cases should help to achieve treatment success. Als...

Odorous waste products such as urine and faeces are unavoidable for most animals and are widely exploited by predators and their prey. Consequently, waste accumulations can be risky and prey which increase their mobility in order to disperse and dilute their waste should avoid a high predation risk...
