The Genets, Paradoxures, Ichneumons, and Suricates are small 

 carnivores varying in their diet from purely carnivorous (in- 

 cluding small mammals, birds, reptiles, eggs, insects) to a mixed 

 and partly frugivorous or vegetarian type. What their potential 

 longevity may be is quite unknown, but the records of maximum 

 duration going to over fifteen years are unexpectedly high for these 

 small animals. The average duration varies very much, but is 

 lower than in the case of the civets. During the period covered 

 by the records, the genets, paradoxures, etc., unlike the civets, have 

 been kept in most cases in a warmed house, without access to the 

 open air.

Nothing is known as to the potential longevity of hyaenas, and 

 the record of 13 years in the Gardens may possibly be a fair age 

 for these animals. They have been kept at the Gardens in cages 

 under cover, exposed on one side to the open air and provided
