Birds that are kept in captivity often require nail trims, presumably due to the lack of opportunity to wear the nails down on natural substrates. For many birds, restraint for the nail trim may result...
The preference of Syrian hamsters (Mesocricetus auratus) for different in-cage shelters was tested. First, 15 males and 15 females were made to choose between a cage with a shelter and one without. Different shelters were...
Offering enrichment to stimulate chewing behavior in rats has been found to promote psychologic and physiologic wellbeing. While there are many commercially produced nylon products available for use as chewable enrichment, these items are costly...
We used four years of detailed data on where 23 great apes (chimpanzees and gorillas) positioned themselves within a modern, indoor/outdoor zoo enclosure to determine not only how the apes utilized their space but also...
Little information is available on the response of vervet monkeys to different housing conditions or on the suitability of enrichment devices or methods for vervet monkeys. In this study, the authors evaluated the occurrence of...
The three main divisions of 'marmosetcare.com' aim respectively to promote: an understanding of the range of behaviour in this species, placing this behaviour in the context of its natural habitat and promoting good welfare in...
Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively in order to defend resources such...
The use of substrate can have benefits to group housed macaques, including decreased aggression and increased foraging. Still, in some facilities, the use of bedding is perceived as time intensive and costly. In this study...
The authors provide an update to their 2006 report on the successful large-scale captive breeding of the 13-lined ground squirrel (TLGS; Ictidomys tridecemlineatus) in their colony, now a single-source supplier of purpose-bred TLGSs for several...
The ideal animal model would contribute no confounding variables in experimental science. Variables affect experimental design resulting in increased animal use or repeated studies. We demonstrated a simple refinement which may reduce the number of...
