It has long cylindrical body, long thin tail and very short legs. Although the absolute number of cats used in research has been in steady decline since 1980, cats are still important models in the neurosciences and in the study of infectious diseases. The most abundant species used were guinea pigs (213,629), rabbits (210,172), and the combination of several species of hamsters (145,895) of which >90% were estimated to be of the Syrian variety. The tail length is always less than the body length. A cardinal rule of laboratory animal science and medicine is to always keep in mind that procedures carried out in health and husbandry programs may have significant effects on research results. The survey results indicate that mouse is the overwhelmingly preferred laboratory animal; the most widely used mouse and rat strains are C57BL/6 mice, BALB/c mice, Sprague-Dawley rats and Wistar rats. ETPLAS is led by laboratory animal scientists and veterinarians, with the goal of providing the best resources and tools for education and training in LAS.

Rabbit: Although the guinea pig (Cavia porcellus) was among the first animals to be used in medical research, its popularity has diminished relative to that of mice and rats because of its long gestation period (59–72 days), small litter size (2–5), poor vascular access, and difficulties in anesthesia. The guinea pig differs from the other laboratory rodents in many respects. Frequently, it is a secondary and complicating factor in the enteritis complex.

Small blood samples can be obtained from a tail vein by snipping the tip of the tail, large quantity of blood can be collected by cardiac puncture or by orbital sinus from anaesthetized rat. An animal chimera is a single organism that is composed of two or more different populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction.If the different cells have emerged from the same zygote, the organism is called a mosaic.Chimeras are formed from at least four parent cells (two fertilised eggs or early embryos fused together). Environmental conditions such as housing and husbandry have a major impact on the laboratory animal throughout its life and will thereby influence the outcome of animal experiments ( Baumans 2004 ; Van de Weerd et al.
