Socialization and problem-solving in domestic cats (Felis catus)
There is evidence that an animal’s socialization towards humans and rearing environment can enhance their problem-solving ability. According to the social intelligence hypothesis, which states that intelligence evolved due to complex social environments, an animal’s social life should result in …

Metabolism and cryo-sensitivity of domestic cat (Felis catus) and cheetah (Acinonyx jubatus) spermatozoa
<p> <p>Teratospermia (ejaculation of ≥ 60% structurally abnormal spermatozoa) is prevalent among felids facing extinction risk, including the cheetah. This trait also occurs in certain domestic cat populations, providing a valuable research model. Multiple components of sperm function are disrupted …

Ecology of feral cats Felis catus and their prey in relation to shrubland fire regimes
… shrublands influences the ecology of feral cats Felis catus, dingoes Canis dingo and their prey species in Western Australia’s northern Wheatbelt region. A review of the literature revealed that feral cats inhabit a diverse range of ecosystems worldwide, but are generally recorded most often in …

Priming with Oral Progestin Before Ovulation Induction Facilitates Ovarian Function in the Cat (Felis catus)
Artificial insemination (AI) has been developed in multiple felid species as a tool for retaining gene diversity in threatened or endangered populations. Yet, pregnancy success remains low (< 5%) following AI in most felids, particularly in species that spontaneously ovulate. This failure has been …

Cape Town's domestic cats : prey and movement patterns in deep-urban and urban-edge areas
Domestic and feral cats (Felis catus) have impacted negatively on native wildlife on both islands and on the mainland. Impacts range from a reduction in numbers of prey species to local extinctions, especially of birds on islands. This study provides the first data on the impacts of domestic cats …

Observing and measuring the drinking mechanism in cats
… of the lapping mechanism in domestic cats (Felis catus). Using high-speed video, digital image processing, and weight measurements we quantify data pertaining to the frequency of lapping and the volume of liquid consumed per lap. These observations allow us to suggest a possible mathematical …

Mobilização rápida de citocromo-oxidase por estimulação sensorial em córtex visual de gatos e primatas
… fast mobilization was studied in twelve cats (Felis catus) and three monkeys (Cebus apella). Visual stimulus of low spatial frequency, with variations in colour and brightness and no spatial orientation allowed the observation of cytochrome oxidase-rich patches in flattened sections of cat's …

Aspects of the ecology and management of small mammalian predators in northern New Zealand
… Chapter I. The prey species of domestic cats (Felis catus) in two suburbs of Auckland city, New Zealand. The prey brought in by 80 cats (Felis catus), over a year was monitored in two suburbs of Auckland New Zealand. The survey technique followed that of Churcher & Lawton (1987) where cat …

Identifikation antigener Determinanten des ZPB2 Proteins der Hauskatze und Charakterisierung ihrer kontrazeptiven und immunogenen Eigenschaften
… Immunokontrazeption von verwilderten Hauskatzen (Felis catus). Dazu wurden zunächst relevante B-Zell-Epitope des felinen Zona pellucida Proteins, ZPB2, identifiziert und synthetisiert. Zwei der synthetischen Peptide (P3, P6) wurden zur Herstellung von Antikörpern an BSA konjugiert und zusammen mit …

Cape Town's cats: reassessing predation through kitty-cams
Domestic cats (Felis catus) are abundant generalist predators that exploit a wide range of prey within and adjacent to the urban matrix. Cats are known to have contributed to the extinction and endangerment (mostly on islands) of a number of indigenous species, including birds, small mammals, …
