Cryopreservation of Domestic Cat Epididymal Spermatozoa
… no egg yolk and could still effectively freeze domestic cat epididymal spermatozoa, for the purpose to sort spermatozoa into X and Y, using flow cytometry. In the first experiment we compared a TesT (Tes + Tris) 20% egg yolk extender (control) to a modified human sperm preservation medium (HSPM) …

Metabolism and cryo-sensitivity of domestic cat (Felis catus) and cheetah (Acinonyx jubatus) spermatozoa
… the cheetah. This trait also occurs in certain domestic cat populations, providing a valuable research model. Multiple components of sperm function are disrupted in teratospermic cats, and even structurally normal spermatozoa from these ejaculates may be functionally compromised. Teratospermic …

Exploring the effects of insulin and glucose on the development of in vitro produced domestic cat embryos
… was in part due to a response specific to the domestic cat. The concentrations of glucose and insulin in oviductal and uterine fluid are related to plasma concentrations so that metabolic conditions such as insulin resistance, hyperglycemia, and type 2 diabetes that affect circulating …

The biochemical systematics of the Southern African Felidae
The classification of the family Felidae (cats) is problematical due to the conservative nature of their morphology. Some workers classify the family into as many as 20 genera (Ewer, 1973) while others divide it into three genera (Walker et al., 1964). Such studies have largely been based on …

Role of endogenous retrovirus in control of feline leukemia virus infection and implications for cross species transmission
… forces have limited the capacity for ERV replication and virulence. While they are seldom considered infectious alone, they maintain the ability to interact with their exogenous retroviral (XRV) progenitors. In Chapter One, we review the interactions that exist between ERV and XRV dyads. One …

Biochemical taxonomy by DNA analysis
… is no general agreement concerning its classification (Ansell, 1971b). Mt DNA restriction analyses were performed on 14 Southern African bovids and restriction maps constructed independently for all 14 species. Phylogenetic trees were constructed by using both distance and cladistic methods. …

Factors affecting replication and cross-species transmission of feline immunodeficiency virus
… restriction factors, dominant blocks to replication, and be able to make use of available host factors such as entry receptors for replication. Human immunodeficiency virus (HIV-1) infection is blocked at a post-entry stage by rhesus macaque TRIM5α, an effect that is enhanced by host factor …

Priming with Oral Progestin Before Ovulation Induction Facilitates Ovarian Function in the Cat (Felis catus)
… used to induce ovulation. Using the domestic cat as a research model, a new AI regimen that incorporated short-term ovarian suppression with oral progestin (altrenogest; ALT) before ovulation induction was investigated. The hypothesis was that oral progestin priming would prevent …

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America
… richness (ESR), and diet using non-invasive scat sampling in a protected forest vs. surrounding non-protected areas in Belize. Field studies relying on non-invasive fecal hormone monitoring are subject to potential hormone degradation in samples exposed to the environment. Therefore I …

Culicoides smulkiųjų mašalų (Diptera: Ceratopogonidae) mitybos analizė /
… The mammal blood meal sources were mainly cattle (Bos taurus), humans (Homo sapiens), and domestic cat (Felis catus). Additionally, the found Culicoides ornithophilic species were C. segnis, C. kibunensis, C. festivipennis and C. pictipennis. Mammalophilic species were C. obsoletus and C. …

The ecology and management of feral cat colonies. A survey of feral cat colonies in Great Britain and an experimental field study of the effect of neutering on the ecology, behaviour and social organisation of a single colony.
A postal questionnaire survey located over 700 feral cat colonies. Most were small well - established and lived in association with man, The feral cat population of Britain was estimated to be one million and is concentrated in urban areas. A domestic cat survey indicated a total population of 5.9 …

Feline Leukemia Virus Detection in Corneal Tissues of Cats by Polymerase Chain Reaction and Immunohistochemistry
… carries a high rate of success in the domestic cat and is an indicated treatment for specific corneal diseases in this species. The potential for iatrogenic transmission of viral diseases is a well-recognized problem in human corneal transplantation programs and screening donors for …

Investigation of spermatozoal metabolism and substrate utilization in domestic and non-domestic felids
… sperm metabolism using semen collected from domestic cats (Felis catus), cheetahs (Acinonyx jubatus), and clouded leopards (Neofelis nebulosa). The main objectives of this research were to: 1) characterize the metabolome of spermatozoa and seminal fluid; 2) investigate the role of β-oxidation …

An Investigation of Environmental Factors that Affect the Behavior and Welfare of Domestic Cats (Felis sylvestris catus)
Domestic cats are the most commonly kept companion animal in the U.S. with large populations of owned (86 million), free-roaming (70 million), research (13,000) and shelter (2-3 million) cats. Therefore, large numbers of cats are confined to cages each year, so offering the most appropriate housing …
