Innovative environmental enrichment method for Pallas cat (Felis manul)

Abstract:

Due to the expansion of the human population we are an increasing threat to all wild animals. They are driven to exist in smaller areas and in the worst case scenario extinction. Zoos are being encouraged to improve the animal’s physical and social surroundings. Environmental enrichment is a term used for such improvements. In this behavioural study, the enrichment introduced to two Pallas cats (Felis manul) at Parken Zoo in Eskilstuna, Sweden, consisted of a fishing rod and a clothes peg with a dead mouse or chick attached. The intention was to see if the feeding enrichment could increase activity levels and how the cats were using their enclosure. The enclosure was divided into seven zones which have a varying degree of opportunities for the animals to climb, hide and rest above ground level. The environmental enrichment effects on the Pallas cats´ behaviour, activity levels and use of the enclosure were measured and recorded using instantaneous scan sampling, and the mean value was calculated for each individual. The behavioural and enclosure results proved that enrichment benefits the cats activity levels. The behaviours that showed a variation when presented with enrichment were: walking, climbing, grooming, aggressive behaviour, out of sight behaviour, crouching position, sitting and standing still.  The results showed that the cats preferred the zones in the enclosure that offered a larger view of the nearby enclosures. This study shows that providing captive felids with inexpensive, easy to administer enrichment objects can have profound effects on activity behaviours and their enclosure.
